  • Extract part of a image from a big image

    - by rajat
    I have a 6 images , and each image has a certain section that i want to save as a separate image , the problem is that it has to be accurate because i am doing some animation using the sub-image so they should exactly . so I want to accurately extract a that part from each of the 6 images , i can't do it using a image editor in which i have to make the bounding box myself because it will not be accurate , is there any program that lets me do this by like defining a box using numerical values. PS: I don't want to write matlab or opencv program for this .

  • Handling Types for Real and Complex Matrices in a BLAS Wrapper

    - by mga
    I come from a C background and I'm now learning OOP with C++. As an exercise (so please don't just say "this already exists"), I want to implement a wrapper for BLAS that will let the user write matrix algebra in an intuitive way (e.g. similar to MATLAB) e.g.: A = B*C*D.Inverse() + E.Transpose(); My problem is how to go about dealing with real (R) and complex (C) matrices, because of C++'s "curse" of letting you do the same thing in N different ways. I do have a clear idea of what it should look like to the user: s/he should be able to define the two separately, but operations would return a type depending on the types of the operands (R*R = R, C*C = C, R*C = C*R = C). Additionally R can be cast into C and vice versa (just by setting the imaginary parts to 0). I have considered the following options: As a real number is a special case of a complex number, inherit CMatrix from RMatrix. I quickly dismissed this as the two would have to return different types for the same getter function. Inherit RMatrix and CMatrix from Matrix. However, I can't really think of any common code that would go into Matrix (because of the different return types). Templates. Declare Matrix<T> and declare the getter function as T Get(int i, int j), and operator functions as Matrix *(Matrix RHS). Then specialize Matrix<double> and Matrix<complex>, and overload the functions. Then I couldn't really see what I would gain with templates, so why not just define RMatrix and CMatrix separately from each other, and then overload functions as necessary? Although this last option makes sense to me, there's an annoying voice inside my head saying this is not elegant, because the two are clearly related. Perhaps I'm missing an appropriate design pattern? So I guess what I'm looking for is either absolution for doing this, or advice on how to do better.

  • What language and topics should be covered when teaching non-CS college students how to program?

    - by michaelcarrano
    I have been asked by many of my non-computer science friends to teach them how to program. I have agreed to hold a seminar for them that will last for approximately 1 to 2 hours. My thoughts are to use Python as the language to teach them basic programming skills. I figured Python is relatively easier to learn from what I have researched. It is also a language I want to learn which will make holding this seminar all the more enjoyable. The topics I plan to cover are as followed: Variables / Arrays Logic - If else statements, switch case, nested statements Loops - for, while, do-while and nested loops Functions - pass by value, pass by reference (is this the correct terms for Python? I am mostly a C/C++ person) Object Oriented Programming Of course, I plan to have code examples for all topics and I will try to have each example flow into each other so that at the end of the seminar everyone will have a complete working program. I suppose my question is, if you were given 1 to 2 hours to teach a group of college students how to program, what language would you choose and what topics would you cover? Update: Thank you for the great feedback. I should have mentioned in my earlier post above that a majority of the students attending the seminar have some form of programming experience whether it was with Java or using Matlab. Most of these students are 3rd/4th year Engineering students who want to get a refresher on programming before they graduate.

  • Diving into a computer science career [closed]

    - by Willis
    Well first I would like to say thank you for taking the time to read my question. I'll give you some background. I graduated two years ago from a local UC in my state with a degree in cognitive psychology and worked in a neuroscience lab. During this time I was exposed to some light Matlab programming and other programming tidbits, but before this I had some basic understanding of programming. My father worked IT for a company when I was younger so I picked up his books and took learned things along the way growing up. Naturally I'm an inquisitive person, constantly learning, love challenges, and have had exposure to some languages. Yet at this point I was fully pursue it as a career and always had this in the back of my head. Where do I start? I'm 25 and feel like I still have time to make a switch. I've immersed myself in the terminal/command prompt to start, but which language do I focus on? I've read the A+ book and planning to take on the exam, then the networking exam, but I want to deal with more programming, development, and troubleshooting. I understand to get involved in open source, but where? I took the next step and got a small IT assistant job, but doesn't really deal with programming, development, just troubling shooting and small network issues. Thank you!

  • Graphical Interface and Object Selection/Manipulation

    - by ToriArendt
    I have a project I want to try to implement, but I'm kind of stuck on how to get started. I know there are probably a lot of resources that I can look at, but I'm really just stuck on what to even search for and where to begin. Basically, I have a program written in Java that separates 3D coordinates from a 3D reconstructed model into different objects. I then want to be able to perform a logistic regression on these objects to determine if they are type A or type B. But first, I need to classify a training set of objects as type A or B by hand. I don't know ANYTHING about graphing or user interfaces in Java, so I have been plotting the coordinates of a given object in MATLAB so that I can visualize the object and assign it a type. Now, as I am trying to make this program more "user friendly" I want to create an interface in Java where I can simply graph all the coordinates of the objects from the entire 3D model (on the same graph). I then want to be able to click on the each object and assign it to be either of type A or type B. I hope this description makes sense and someone can point me in the direction of something that will help me. I'm sorry if some of this terminology is off; I'm a bit new to software development. P.S. If anyone also has some tips on implementing logistic regression in Java, I'm sure I'll need them down the road :).

  • Any benefit of /home Ubuntu partition

    - by nightcrawler
    I want to have dual OS of Win8 & Ubuntu 12.10. Provided that Ubuntu can access ntfs partition of Windows but same can't be said about Windows this leads to a question mark on the significance of having /home partition while installing Ubuntu. As far as I know /swap & / are the two partitions directly used by Ubuntu to store programs, installation & stuff while the documents/media resides in /home. Now because Ubuntu releases are more frequent than Windows & updates needs backup & relate stuff, so I came to decision to not to use /home at all, rather keep all my documents/media in ntfs, which would be untouched while upgrading Ubuntu as Win updates are once in a decade! Is my thinking correct? If yes, what would be the minimum space I should allot to /home plus how much I should allot to / one must know that I plan to use heavy applications like Maple, Matlab & Sagemath on Ubuntu.

  • Simple command line calculator

    - by ldigas
    Had one years ago (on Win 3.1 or '95, I'm not sure). Anyways, it was a really simple program. Stood somewhere in PATH and enabled you to do something of a kind calc 5 + 28.3*sqrt(12) and it spit out the result. Anyone know of any such these days? Doesn't need to do anything fancy ... maybe it would just be nice if it had support for exponentials, but that's it. Anyone? p.s. Not interested in full blown solutions like Python or MATLAB.

  • Windows 7 tasks don't switch when clicking window

    - by Jonathan Weinraub
    I got a peculiar problem with an enduser today. He says for the past month or so, if he has a window open (not maximised) and he clicks the window below it (also not maximised), it won't switch to it. For example, if he is in Lotus Notes, and wants to go back to Firefox, and he clicks the Firefox title bar, the tasks don't change focus/switch to it. This doesn't happen for applications. Usually it is with Firefox but if he's in Matlab and goes to PADS for example, they switch fine. If you close the apps, and reopen them, it'll work, but about 30 minutes later the weirdness then resumes. Any insight would be greatly appreciated. Thanks!

  • Will you install software on the same partition as Windows system?

    - by Tim
    I was wondering if you always install software on the same partition as Windows 7 system? What kinds of software do you install on the same partition as Windows system? What kinds of software you install on another partition? If you install software on another partition, do you install them on a dedicated partition to these software? Or do you install them on the same partition as data (personal data)? How do you plan the sizes for the partition(s) in either case? What are to consider when making plans about the above questions? The software I am installing include: Matlab, Mathematica, IDEs, compilers or Interpreters for C++, C, Java, R, Python, Perl, Lisp, Latex, and database. Mainly for programming and typesetting kinds of studies and projects.

  • Laser range finder, what language to use? Beginner advice

    - by DrOnline
    I hope this is the right place. I am a programming beginner, and I want to make a laser range finder, and I need advice about how to proceed etc. In a few weeks I will get a lot of dirt cheap 3-5V lasers and some cheap usb webcams. I will point the laser and webcam in parallel, and somehow use trigonometry and programming to determined distance. I have seen online that others made done it this way, I have purposefully not looked at the details too much because I want to develop it on my own, and learn, but I know the general outline. I have a general idea of how to proceed. The program loads in a picture from the webcam, and I dunno how images work really, but I imagine there is a format that is basically an array of RGB values.. is this right? I will load in the red values, and find the most red one. I know the height difference between the laser and the cam. I know the center dot in the image, I know the redmost dot. I'm sure there's some way to figure out some range there. TO THE POINT: 1) Is my reasoning sound thus far, especially in terms of image analysis? I don't need complete solutions, just general points 2) What I need to figure out, is what platform to use. I have an arduino... apparently, I've read it's too weak to process images. Read that online. I know some C I know some Python I have Matlab. Which is the best option? I do not need high sampling rates, I have not decided on whether it should be automated or whether I should make a GUI with a button to press for samples. I will keep it simple and expand I think. I also do not need it to be super accurate, I'm just having fun here. Advice!

  • How to parse amadeus air ticket file

    - by Andrus
    Amadeous produces AIR file like below for every flyight reservation. I need to read reservation number and source and destionation airports from this file. I searched goog for "amadeous air format" but havent found format description. Wikipedia entry about EDIFACt is a bit different, it does not describe this content. Where to fnd information about the file structure ? How to parse this file ? I have not idea about the file stucture, does it contain records like sql table or is it some reservation protocol instructions like postscript file ? Application should work in Microsoft Windows and preferably in Visual FoxPro or C# language. FoxPro or Microsoft Visual Studio 2012 Express can used as programming environment Google returns only Amadeus users guides and tutorials like in comment and in http://www.amadeusschweiz.com/en/documentation/usermanuals.html Those are user manuals. Most promising looks Amadeus Air user guide from this: File which I received name was air.txt and first token in file is AIR-BLK206 Maybe BLK206 is some booking format descriptor. Google returns some documens like my using this so it looks like it is commonly used. This file probably describes how to reserve ticket, which produces air.txt file. I seacrched this and ticket user guide for BLK but those do not contains this abbreviation. Commands in user manual look different than those from this file. How to use this information to extract reservation number and destination airport from this file ? I havent found format description using google. There are amadeus user guides, tutorials ja quick reference files similar which you posted but I do'nt understand how to use them to parse this file. One message describes that this is form of EDIFACT. However EDIFACT message sample in Wikipedia is also diffrerent. I need to create quick prototype to customer which shows that we vcan read those files. Maybe there are some programs which can used to display it in human readable form ?

  • OS X, Mercurial and MediaTemple problem

  • How does Silverlight Image Clipping work?

    - by TreeUK
    I've got a very large image which I'd like to use for sprite techniques (à la css image sprites). I've got the code below: <Image x:Name="testImage" Width="24" Height="12" Source="../Resources/Images/sprites.png"> <Image.Clip> <RectangleGeometry Rect="258,10632,24,12" /> </Image.Clip> </Image> This clips the source image to 24x12 at the relative position of 258, 10632 in the source image. The problem is that I want the cropped image to show at 0,0 in the testImage whereas it shows it at 258, 10632. It's using the geometry as a cutting guide but also as a layout guide. Anyone have any idea how this should be done? if at all. Conclusion: There seems to be no good way of doing this at present, Graeme's solution seems to be the closest to achieving this with Silverlight 2.0. That said, if anyone knows of a better way of doing this, please reply with an answer.

  • Selection Highlight in NSCollectionView

    - by Hooligancat
    On some occasions my head just hurts from banging it against the Cocoa wall. Today is one of those days. I have a working NSCollectionView with one minor, but critical, exception. Getting and highlighting the selected item within the collection. I've had all this working prior to Snow Leopard, but something appears to have changed and I can't quite place my finger on it, so I took my NSCollectionView right back to a basic test and followed Apple's documentation for creating an NSCollectionView here: http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CollectionViews/Introduction/Introduction.html The collection view works fine following the quick start guide. However, this guide doesn't discuss selection other than "There are such features as incorporating image views, setting objects as selectable or not selectable and changing colors if they are selected". Using this as an example I went to the next step of binding the Array Controller to the NSCollectionView with the controller key selectionIndexes, thinking that this would bind any selection I make between the NSCollectionView and the array controller and thus firing off a KVO notification. I also set the NSCollectionView to be selectable in IB. There appears to be no selection delegate for NSCollectionView and unlike most Cocoa UI views, there appears to be no default selected highlight. So my problem really comes down to a related issue, but two distinct questions. How do I capture a selection of an item? How do I show a highlight of an item? NSCollectionView's programming guides seem to be few and far between and most searches via Google appear to pull up pre-Snow Leopard implementations, or use the view in a separate XIB file. For the latter (separate XIB file for the view), I don't see why this should be a pre-requisite otherwise I would have suspected that Apple would not have included the view in the same bundle as the collection view item. I know this is going to be a "can't see the wood for the trees" issue - so I'm prepared for the "doh!" moment. As usual, any and all help much appreciated.

  • Help/Questions About New Team Foundation Server 2010 Installation

    - by user579218
    Hello. Before starting down the TFS2010 installation process, I have a few questions I'm hoping the community can help me with. We're planning on a single-server installation of TFS2010. Initially, we want version/source control and build services, but not reporting or SharePoint. We may add reporting and SharePoint capabilities later. Our environment will be Windows Server 2008 R2 (x64), SQL Server 2008 R2 (x64), Office 2010 (x86), Visual Studio 6 and 2010, and, of course, Team Foundation Server 2010. Can I install TFS2010 on a server that is on our domain? It's not a domain controller, it's just a member server on the domain. Should I install TFS2010 before or after putting the server on the domain? We have six developers that will be logging into their local development computers (which are also on the same domain) using their domain user accounts, do I add each domain user to the TFS2010 server's security groups? If so, which one(s)? Can I or should I use a domain user account as the TFS2010 service account? Or, should I just use Network Service? The TFS2010 install guide notes that none of the service accounts should belong to the Administrators security group, so which security group(s) are recommended for the service account(s)? We're planning on using a local instance of SQL Server 2008 R2 Standard with TFS2010, what service account should we use? Should we use the same domain account as TFS2010 or Local System or ?? The TFS2010 install guide isn't very specific on this. Since we're planning on this server being both the version/source control and build server, should we install our development environments (VS6, VS2010, Access2010) before installing TFS2010? Or does it matter? Thanks in advance for answering these questions.

  • How to implement YQL paging?

    - by Erik Vold
    I've read the YQL guide, and I keep reviewing http://developer.yahoo.com/yql/guide/yql-o...entables-paging and I have been looking at a few examples, but I'm still left pretty confused how YQL paging works. The problem that I am trying to tackle is creating a YQL open data table for the Mozilla labs Jetpack Gallery's jetpacks pages http://jetpackgallery.mozillalabs.com/jetpacks You flip through the pages of jetpacks with the ?page query variable and there is an order_by query variable. You can only see 10 results per page. Questions: List item Should I use or ? How do I specify the query parameter that indicates the page? in this case it is the 'page' query parameter. I am assuming I should use: <urls><url>http://jetpackgallery.mozillalabs.com/jetpacks</url></urls> is this correct? In the execute element, I will need to extract the details for each jetpack on the page? if so how would I organize that for the response.object? Can anyone provide some help? or perhaps point to a data table that I can look at as a reference? or better documentation on how paging works?

  • Using section header in Sendgrid

    - by Zefiryn
    I am trying to send emails through sendgrid in Zend application. I copy the php code from the sendgrid documentation (smtapi class and swift). I create a template with places that should be substituted with %variable%. Now I create headers for sendgrid as defined here: http://docs.sendgrid.com/documentation/api/smtp-api/developers-guide/ In result I get something looking like this: { "to": ["[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]"], "sub": {"%firstname%": ["Benny", "Chaim", "Ephraim", "Yehuda", "will"]}, "section": {"%postername%": "Rabbi Yitzchak Lieblich", "%postermail%": "[email protected]", "%categoryname%": "General", "%threadname%": "Completely new thread", "%post%": "This thread is to inform you about something very important", "%threadurl%": "http:\/\/hb.local\/forums\/general\/thread\/143", "%replyto%": "http:\/\/hb.local\/forums\/general\/thread\/143", "%unsubscribeurl%": "http:\/\/hb.local\/forums\/settings\/", "%subscribeurl%": "http:\/\/hb.local\/forums\/subscribe-thread\/id\/143\/token\/1b20eb7799829e22ba2d48ca0867d3ce"} } Now while all data defined in "sub" changes I cannot make section work. In the final email I still got %postername%. When I move this data to sub and repeat them for each email everything is working fine. Has anyone a clue what I am doing wrong?

  • Validation using JAXB and Stax to marshal XML document

    - by bajafresh4life
    I have created an XML schema (foo.xsd) and used xjc to create my binding classes for JAXB. Let's say the root element is "collection" and I am writing N "document" objects, which are complex types. Because I plan to write out large XML files, I am using Stax to write out the "collection" root element, and JAXB to marshal document subtrees using Marshaller.marshal(JAXBElement, XMLEventWriter). This is the approach recommended by jaxb's unofficial user's guide: https://jaxb.dev.java.net/guide/Different_ways_of_marshalling.html#Marshalling_into_a_subtree My question is, how can I validate the XML while it's being marshalled? If I bind a schema to the JAXB marshaller (using Marshaller.setSchema()), I get validation errors because I am only marshalling a subtree (it's complaining that it's not seeing the "collection" root element"). I suppose what I really want to do is bind a schema to the Stax XMLEventWriter or something like that. Any comments on this overall approach would be helpful. Basically I want to be able to use JAXB to marshal and unmarshal large XML documents without running out of memory, so if there's a better way to do this let me know.

  • Storing data on SD Card in Android

    - by BBoom
    Using the guide at Android Developers (http://developer.android.com/guide/topics/data/data-storage.html) I've tried to store some data to the SD-Card. This is my code: // Path to write files to String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/"+ctxt.getString(R.string.package_name)+"/files/"; String fname = "mytest.txt"; // Current state of the external media String extState = Environment.getExternalStorageState(); // External media can be written onto if (extState.equals(Environment.MEDIA_MOUNTED)) { try { // Make sure the path exists boolean exists = (new File(path)).exists(); if (!exists){ new File(path).mkdirs(); } // Open output stream FileOutputStream fOut = new FileOutputStream(path + fname); fOut.write("Test".getBytes()); // Close output stream fOut.flush(); fOut.close(); } catch (IOException ioe) { ioe.printStackTrace(); } When I create the new FileOutputStream I get a FileNotFound exception. I have also noticed that "mkdirs()" does not seem to create the directory. Can anyone tell me what I'm doing wrong? I'm testing on an AVD with a 2GB sd card and "hw.sdCard: yes", the File Explorer of DDMS in Eclipse tells me that the only directory on the sdcard is "LOST.DIR".

  • Nexus One & Windows XP USB Driver

    - by Stefan
    I've been unable to get my Nexus One working as a development phone on Windows XP. I've got the driver (revision 3 for N1 support), I've got it installed according to the official installation guide, and the phone appears in the Device Manager just as the guide says it should. However, adb still can't find the phone. 'adb devices', for example, returns no active devices. Am I forgetting some basic step? One thing I've noticed is that the driver is labeled in Windows as version 2 released November, 2009 (I need version 3 from January 2010 for N1 support). However, I've never had version 2 installed. I've used the SDK to download version 3 several times - even deleted it and redownloaded it. I've uninstalled/reinstalled the version 3 driver multiple times. It still says version 2. Is this the problem, or this something completely unrelated? Note: The phone is working as a dev phone on Ubuntu, so I know the phone/cable/etc. are good. It's either my fault or the driver's.

  • Sysdeo Tomcat DevLoader - Hot deploy of java class causes whole application to restart

    - by Gala101
    Hi, I am using sysdeo tomcat plugin 3.2.1 with eclipse 3.5.1 (Galileo) and tomcat 5.5.23 on windows XP. I can get tomcat plugin working in eclipse, and have extracted devloader.zip into [tomcat]\server\classes. I have also updated the context and now it has this entry: <Context path="/myapp1" reloadable="true" docBase="F:\Work\eclipse_workspace\myapp1" workDir="F:\Work\eclipse_workspace\myapp1\work" > <Logger className="org.apache.catalina.logger.SystemOutLogger" verbosity="4" timestamp="true"/> <Loader className="org.apache.catalina.loader.DevLoader" reloadable="true" debug="1" useSystemClassLoaderAsParent="false" /> </Context> I have activated devloader (in Project Properties Tomcat Devloader Classpath) and have 'checked' all my classes and jars, I haven't 'checked' commons-loggin.jar jsp-api.jar, servlet-api.jar. So on launching tomcat via the plugin, I can get it running with devloader as shown in eclipse console view [DevLoader] Starting DevLoader [DevLoader] projectdir=F:\Work\eclipse_workspace\myapp1 [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/classes/ [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/lib/activation.jar However, if I even add a single System.out.println into any java file and save it, the whole application gets reloaded (takes ~80 sec) which is as good as stopping/starting tomcat itself. I've tried adding -Xdebug in JAVA_OPTS in the catalina.bat but no luck :( Can you please guide where I may be doing it wrong.. Please note that I can 'redeploy' the whole application on tomcat but that's not what I need, I am looking to be able to make small changes in java classes 'on-the-fly' while coding/debugging without having to wait for complete app restart. Another annoyance is that restarting tomcat/application causes the session/debug progress to be lost.. Can you please guide me how to go about it. PS: I am not using any ant/maven scripts explicitly, just relying on eclipse to do the build for me (which it does).

  • Learning about the low level

    - by Anoners
    I'm interested in learning more about the PC from a lower (machine) level. I graduated from a school which taught us concepts using the Java language which abstracted out that level almost completely. As a result I only learned a bit from the one required assembly language course. In order to cram in ASM and quite a few details about architecture, it was hard to get a very deep picture of what is going on there. At work I focus on unix socket programming in C, so i'm much closer to the hardware now, but I feel I should learn a bit more about what streams really are, how memory management and paging works, what goes on when you call "paint()" on a graphics buffer, etc. I missed out on a lot of this and i'm looking for a good resource to get me started. I've heard a lot about the "Pink Book" by Peter Norton (Programmer's Guide to the IBM PC, Programmer's Guide to inside the PC, etc). It seems like this is on the right track, however the original is quite out dated and the newer ones have had conflicting reviews, with many people saying to stay away from it. I'm not sure what the SO crowd thinks about this book or if they have some suggestions for similar books, online resources, etc that may be good primers for this sort of thing. Any suggestions would be appreciated.

  • Nginx rewrite for link shortener and Wordpress

    - by detusueno
    I'm a complete newbie to Nginx, so much so that I followed a online guide to do most of my server setup. I'm trying to learn but I'm still a ways away from understanding it all. So what I'm trying to create is a link shortener that redirects (example.com/x) to (example.com/short.php?id=x). Keep in mind that I'm also running a Wordpress blog on the same domain and plan on using the redirects/shortening for external links. The guide has so far had me add the following rewrites to enable Wordpress pretty URLs: # WordPress pretty URLs: (as per dominiek.com) if (-f $request_filename) { break; } if (-d $request_filename) { break; } rewrite ^(.+)$ /index.php?q=$1 last; # Enable nice permalinks for WordPress: (as per Yawn.it) error_page 404 = //index.php?q=$uri; And if it matters any, it was saved at (/usr/local/nginx/conf/wordpress_params.regular). Additionally, my Wordpress link structure adds "news" to all internal links (example.com/news/post-blah, example.com/news/category, ect.). What's the best way to tackle this setup?
