  • OpenCV Video capture and fps problem

    - by Andrea Girardi
    Hi to all, I'm capturing video from my webcam using OpenCV on MacOSX. It works fine but when I try to play on QuickTime my captured video it plays too fast. i.e. I capture from camera for 10 seconds but when I play on QuickTime the video is 2 seconds. I've tried to change fps from 25 to 10 and It's works quite fine, but I'm sure it's not the correct process: CvVideoWriter *writer = 0; int isColor = 1; int fps = 25; int frameW = 640; // 744 for firewire cameras int frameH = 480; // 480 for firewire cameras The problem is that for now I've to capture with WebCam but the real pourpose of program is to capture image from any external source connected to my Mac. I'm using this code to capture: for (;;) { cvGrabFrame(capture) image = cvRetrieveFrame(capture); cvWriteFrame( writer, image ); } Any hint? I'm also showing webcam output on cvNamedWindow, how can I improve quality in this windows? thanks a lot to all! Andrea!

  • Add shadow to UIImage drawn in rounded path

    - by Tom Irving
    I'm drawing a rounded image in a UITableView cell like so: CGRect imageRect = CGRectMake(8, 8, 40, 40); CGFloat radius = 3; CGFloat minx = CGRectGetMinX(imageRect); CGFloat midx = CGRectGetMidX(imageRect); CGFloat maxx = CGRectGetMaxX(imageRect); CGFloat miny = CGRectGetMinY(imageRect); CGFloat midy = CGRectGetMidY(imageRect); CGFloat maxy = CGRectGetMaxY(imageRect); CGContextMoveToPoint(context, minx, midy); CGContextAddArcToPoint(context, minx, miny, midx, miny, radius); CGContextAddArcToPoint(context, maxx, miny, maxx, midy, radius); CGContextAddArcToPoint(context, maxx, maxy, midx, maxy, radius); CGContextAddArcToPoint(context, minx, maxy, minx, midy, radius); CGContextClosePath(context); CGContextClip(context); [self.theImage drawInRect:imageRect]; This looks great, but I'd like to add a shadow to it for added effect. I've tried using something along the lines of: CGContextSetShadowWithColor(context, CGSizeMake(2, 2), 2, [[UIColor grayColor] CGColor]); CGContextFillPath(context); But this only works when the image has transparent areas, if the image isn't transparent at all, it won't even draw a shadow around the border. I'm wondering if there is something I'm doing wrong?

  • controller path not found for static images? asp.net mvc routing issue?

    - by rksprst
    I have an image folder stored at ~/Content/Images/ I am loading these images via <img src="/Content/Images/Image.png" /> Recently, the images aren't loading and I am getting the following errors in my error log. What's weird is that some images load fine, while others do not load. Anyone have any idea what is wrong with my routes? Am I missing an ignore route for the /Content/ folder? I am also getting the same error for favicon.ico and a bunch of other image files... <Fatal> -- 3/25/2010 2:32:38 AM -- System.Web.HttpException: The controller for path '/Content/Images/box_bottom.png' could not be found or it does not implement IController. at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(Type controllerType) at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContextBase httpContext) at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContext httpContext) at System.Web.Mvc.MvcHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext httpContext) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) My current routes look like this: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "ControllerDefault", // Route name "{controller}/project/{projectid}/{action}/{searchid}", // URL with parameters new { controller = "Listen", action = "Index", searchid = "" } // Parameter defaults ); Thanks!

  • Making mercurial subrepositories behave like subversion externals

    - by Emily Dickinson
    Hi guys, The FAQ, and hginit.com have been really useful for helping me make the transition from svn to hg. However, when it comes to using Hg's subrepository feature in the manner of subversion's externals, I've tried everythign and cannot replicate the nice behavior of svn externals. Here's the simplest example of what I want to do: Init "lib" repository This repository is never to be used as a standalone; it's always included by main repositories, as a sub-repository. Init one or more including repositories To keep the example simple, I'll "init" a repository called "main" Have "main" include "lib" as a subrepository Importantly -- AND HERE'S WHAT I CAN'T GET TO WORK: When I modify a file inside of "main/lib", and I push the modification, then that change gets pushed to the "lib" repository -- NOT to a copy inside of "main". Command lines speak louder than words. I've tried so many variations on this theme, but here's the gist. If someone can reply, in command lines, I'll be forever grateful! 1. Init "lib" repository $ cd /home/moi/hgrepos ## Where I'm storing my hg repositories, on my main server $ hg init lib $ echo "foo" lib/lib.txt $ hg add lib $ hg ci -A -m "Init lib" lib 2. Init "main" repository, and include "lib" as a subrepos $ cd /home/moi/hgrepos $ hg init main $ echo "foo" main/main.txt $ hg add main $ cd main $ hg clone ../lib lib $ echo "lib=lib" .hgsub $ hg ci -A -m "Init main" . This all works fine, but when I make a clone of the "main" repository, and make local modifications to files in "main/lib", and push them, the changes get pushed to "main/lib", NOT to "lib". IN COMMAND-LINE-ESE, THIS IS THE PROBLEM: $ /home/moi/hg-test $ hg clone ssh://[email protected]/hgrepos/lib lib $ hg clone ssh://[email protected]/hgrepos/main main $ cd main $ echo foo lib/lib.txt $ hg st M lib.txt $ hg com -m "Modified lib.txt, from inside the main repos" lib.txt $ hg push pushing to ssh://[email protected]/hgrepos/main/lib That last line of output from hg shows the problem. It shows that I've made a modification to a COPY of a file in lib, NOT to a file in the lib repository. If this were working as I'd like it to work, the push would be to hgrepos/lib, NOT to hgrepos/main/lib. I.e., I would see: $ hg push pushing to ssh://[email protected]/hgrepos/lib IF YOU CAN ANSWER THIS IN TERMS OF COMMAND LINES RATHER THAN IN ENGLISH, I WILL BE ETERNALLY GRATEFUL! Thank you in advance! Emily in Portland

  • memory warning, generating UIImagefrom pdf files in objective-c

    - by favo
    When converting PDF Pages into UIImages I receive memory warnings all the time. It seems there is either some leak or something else that eats my memory. Using instruments didn't give me any helpful details. I'm using the following function to generate images from a pdf file: - (UIImage*)pdfImage:(NSString*)pdfFilename page:(int)page { CFURLRef pdfURL = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, (CFStringRef)pdfFilename, kCFURLPOSIXPathStyle, false); CGPDFDocumentRef pdfRef = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CFRelease(pdfURL); CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfRef, page); CGRect pdfPageSize = CGPDFPageGetBoxRect(pdfPage, kCGPDFBleedBox); float pdfScale; if ( pdfPageSize.size.width < pdfPageSize.size.height ) { pdfScale = PDF_MIN_SIZE / pdfPageSize.size.width; } else { pdfScale = PDF_MIN_SIZE / pdfPageSize.size.height; } CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, pdfPageSize.size.width*pdfScale, pdfPageSize.size.height*pdfScale, 8, (int)pdfPageSize.size.width*pdfScale * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); // CGContextClipToRect(context, pdfPageView.frame); // CGPDFPageRetain(pdfPage); CGAffineTransform transform = aspectFit(CGPDFPageGetBoxRect(pdfPage, kCGPDFBleedBox), CGContextGetClipBoundingBox(context)); CGContextConcatCTM(context, transform); CGContextDrawPDFPage(context, pdfPage); // CGPDFPageRelease (pdfPage); CGImageRef image = CGBitmapContextCreateImage(context); CGContextRelease(context); UIImage *finalImage = [UIImage imageWithCGImage:image]; CGImageRelease(image); CGPDFDocumentRelease(pdfRef); return finalImage; } I am releasing the document and everything else, so where could be the problem? Thanks for your help!

  • Nested UIScrollView-iPhone photos application

    - by abhishek trivedi
    Hi, I have been facing the same nested UIScrollView problem for long time.I tried some open source codes like Scrolling madness ,three-20 and others but all fails finaly.I am trying to make a photo Viewer application same as iPhone.For that I have created the structure like this:- 1)one View controller. 2)on view of view controller one UIScrollView (i.e inner/parent scroll view) as a child. 3)on inner/parent scroll view number of child scroll views(i.e. outer/child scroll views) ,each represents one page of photos application. 4)On each scroll view one image View on which i am displaying my image. So what I want is when user scrolls the outer scroll view it should scroll horizontally with all the child views so I will get the look and feel of paging in photos application.Also when user is on one specific image(i.e. child/outer scroll view) he should be able to zoom in/out,swipes and perform single/double tapping.I was able to make it work in sdk 2.1,but it dosnt work since sdk 3.0.Please tell me the idea behind your project.Means which scroll view you are subclassing ,in which view to detect touches.How this completely child - parent relation should be. If possible provide any sample code also.

  • PrintableArea in C# - Bug?

    - by Brandi
    I am having an issue with PageSettings.PrintableArea's width and height values. Width, Height, and Size properties claim to "get or set" the values. Also, the inflate() function claims to change the size based on values passed in. However, all of these attempts to change the value have not worked. Inflate() is ignore (no error, just passes as if it worked, but the values remain unchanged. Attempting to set the height, width, or size gives a compiler error: "Cannot modify the return value of 'System.Drawing.Printing.PageSettings.PrintableArea' because it is not a variable". I get the feeling that this means the "or set" part of the description is a lie. Why I want to know this: (Someone always asks...) I have a printing application (C#, WinForm) that for most things is working rather well. I can set the printer settings and page settings objects to control what displays in the print dialog's printer properties. However, with Microsoft Office Document Image Writer, these settings are sometimes ignored, and the paper size returns as 0, 0 even when it displayed something else. All I really want it for it to be WYSIWYG as far as the displayed values go, so I change the paper size back to what it should be, but the printable area, if it is wrong, makes the resulting image wonky. The resulting image is the size of the printable area instead of the value in papersize. Just wondering if there was a reason for this or a way to get it not to do that. Thanks in advance. :)

  • can't figure out serving static images in django dev environment

    - by photographer
    I've read the article (and few others on the subject), but still can't figure out how to show an image unless a link to a file existing on a web-service is hard-coded into the html template. I've got in urls.py: ... (r'^galleries/(landscapes)/(?P<path>.jpg)$', 'django.views.static.serve', {'document_root': settings.MEDIA_URL}), ... where 'landscapes' is one of the albums I'm trying to show images from. (There are several more of them.) In views.py it calls the template with code like that: ... <li><img src=160.jpg alt='' title='' /></li> ... which resolves the image link in html into: http://127.0.0.1:8000/galleries/landscapes/160.jpg In settings.py I have: MEDIA_ROOT = 'C:/siteURL/galleries/' MEDIA_URL = 'http://some-good-URL/galleries/' In file system there is a file C:/siteURL/galleries/landscapes/160.jpg and I do have the same file at http://some-good-URL/galleries/landscapes/160.jpg No matter what I use in urls.py — MEDIA_ROOT or MEDIA_URL (with expectation to have either local images served or from the web-server) — I get following in the source code in the browser: <li><img src=160.jpg /></li> There is no image shown in the browser. What am I doing wrong?

  • Calculating skew of text OpenCV

    - by Nick
    I am trying to calculate the skew of text in an image so I can correct it for the best OCR results. Currently this is the function I am using: double compute_skew(Mat &img) { // Binarize cv::threshold(img, img, 225, 255, cv::THRESH_BINARY); // Invert colors cv::bitwise_not(img, img); cv::Mat element = cv::getStructuringElement(cv::MORPH_RECT, cv::Size(5, 3)); cv::erode(img, img, element); std::vector<cv::Point> points; cv::Mat_<uchar>::iterator it = img.begin<uchar>(); cv::Mat_<uchar>::iterator end = img.end<uchar>(); for (; it != end; ++it) if (*it) points.push_back(it.pos()); cv::RotatedRect box = cv::minAreaRect(cv::Mat(points)); double angle = box.angle; if (angle < -45.) angle += 90.; cv::Point2f vertices[4]; box.points(vertices); for(int i = 0; i < 4; ++i) cv::line(img, vertices[i], vertices[(i + 1) % 4], cv::Scalar(255, 0, 0), 1, CV_AA); return angle; } When I look at then angle in debug I get 0.000000 However when I give it this image I get proper results of a skew of about 16 degrees: How can I properly detect the skew in the first image?

  • WPF Update Binding when Bound directly to DataContext w/ Converter

    - by Adam
    Normally when you want a databound control to 'update,' you use the "PropertyChanged" event to signal to the interface that the data has changed behind the scenes. For instance, you could have a textblock that is bound to the datacontext with a property "DisplayText" <TextBlock Text="{Binding Path=DisplayText}"/> From here, if the DataContext raises the PropertyChanged event with PropertyName "DisplayText," then this textblock's text should update (assuming you didn't change the Mode of the binding). However, I have a more complicated binding that uses many properties off of the datacontext to determine the final look and feel of the control. To accomplish this, I bind directly to the datacontext and use a converter. In this case I am working with an image source. <Image Source="{Binding Converter={StaticResource ImageConverter}}"/> As you can see, I use a {Binding} with no path to bind directly to the datacontext, and I use an ImageConverter to select the image I'm looking for. But now I have no way (that I know of) to tell that binding to update. I tried raising the propertychanged event with "." as the propertyname, which did not work. Is this possible? Do I have to wrap up the converting logic into a property that the binding can attach to, or is there a way to tell the binding to refresh (without explicitly refreshing the binding)? Any help would be greatly appreciated. Thanks! -Adam

  • Rendering UIImage/CGImage into CGPDFContext results in... blankness!

    - by quixoto
    Hi all, I'm trying to take an image that I have in a image object and render into a Core Graphics PDF context-- happens to be on an iPhone but this question surely applies equally to desktop Quartz. This UIImage is a simple color-on-white image at about 600x800 resolution. If I (say) turn it into a PNG file, that file looks exactly as expected-- so the data is OK. Here's what I'm doing to generate the PDF: NSMutableData * outputData = [[NSMutableData alloc] init]; CGDataConsumerRef dataConsumer = CGDataConsumerCreateWithCFData((CFMutableDataRef)outputData); CFMutableDictionaryRef attrDictionary = NULL; attrDictionary = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionarySetValue(attrDictionary, kCGPDFContextTitle, @"My Awesome Document"); CGContextRef pdfContext = CGPDFContextCreate(dataConsumer, NULL, attrDictionary); CFRelease(dataConsumer); CFRelease(attrDictionary); CGImageRef pageImage = [myUIImage CGImage]; CGPDFContextBeginPage(pdfContext, NULL); CGContextDrawImage(pdfContext, CGRectMake(0, 0, [myUIImage size].width, [myUIImage size].height), pageImage); CGPDFContextEndPage(pdfContext); CGContextRelease(pdfContext); Resulting PDF, which ends up in outputData, seems like a valid PDF file (opens correctly, document title is present in metadata), but it consists of precisely one blank page. What am I doing wrong? Thanks.

  • Problem with Tapestry palette's arrow icons in IE8

    - by JellyHead
    I'm using Tapestry to create pages for a web app, and have been using the palette component to add/delete items to/from a group. The page looks great in Firefox (Tapestry seems biased towards Firefox), but my customers will all be using Internet Explorer (any versions from 6, 7, & 8) and in IE8, the disabled arrow buttons look awful. In Firefox, they are faded, using an opacity setting of 25%, but this doesn't work in IE8 and instead you get a faded image with an ugly black border around the image. In tapestry-core's stylesheet (default.css), you have the following for a disabled arrow button. DIV.t-palette-controls BUTTON[disabled] IMG { filter: alpha(opacity = 25); -moz-opacity: .25; } These are clearly out of date, as -moz-opacity is no longer supported by Firefox (use opacity: 25 instead). The problem is with filter: "alpha(opacity = 25);". If I remove this, the arrows look fine in IE8, but they are not faded. I got the magic instruction: -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=25)"; from various websites, but putting this in does not work either - the arrow icons are ugly again. The icon itself (distributed with Tapestry) just seems to be a regular PNG, but I'm not an expert on image formats, so maybe there's a problem there? Anyone else had this problem?

  • Android:Multi touch doesn't work as expected?

    - by user187532
    Hi folks, Help me in resolving the below issue. I have three image buttons on screen. All these three buttons controlled under ontouchlistner as below. buttonOne.setOnTouchListener(this); buttonTwo.setOnTouchListener(this); buttonThree.setOnTouchListener(this); I override "public boolean onTouch(View v, MotionEvent event)". Under this i check for these three image buttons touch events like below. ImageButton imageBtn = (ImageButton) v; if ( imageBtn == buttonOne ) // first button touch ..Log.. else if ( imageBtn == buttonTwo ) ..Log.. else if ( imageBtn == buttonThree ) // first button touch ..Log.. My problem is, as it is under multi touch event handler like above, it does not detect when touch all three button at a time to try to produce multi touch effect, instead it detects only one imagebutton touch at a time even though i touch all three image buttons. As i am developing this project on Android 1.6 SDK, is there any problem accessing my requirement(multi touch) (or) it is a known issue? I am hoping that, when it works for single button touch, why shouldn't it work when clicking three imagebuttons at a time to produce three logs printed as per my above code? How do i resolve it for my case? Please don't question me why i am still developing on 1.6 for such a requirement. Thank you. Appreciate your suggestions !

  • Caching a user control

    - by Rishabh Ohri
    I have a user control which I want to Output cache( fragment cache) and set the dependency to a query. I mean that on change or modification of data returned by that query the cache should get invalidated. I have read that in the output cache directive in the user control Sqldependency = "CommandNotification" cannot be used. So, how should i proceed in order to add the sql query dependency to the fragment cached user control.

  • Quartz compositions created in Snow Leopard (10.6) doesn't work in Leopard (10.5) despite testing in

    - by adib
    Hi I have a reasonably advanced (many patches and subpatches) quartz composition that was created in Snow Leopard but doesn't run well (many elements are not rendered) in Leopard. The composition tested OK via Quartz Composer's Test in Runtime option and works fine for both Leopard 32-bits and Leopard 64-bits (menu item "File | Test in Runtime | Leopard 32-bits". In an actual Leopard (32-bits) system, a lot of elements are not rendered in the quartz composition. Below are the log file excerpt when the composition is run in QuickTime Player under Leopard: QuickTime Player[134] *** <QCNodeManager | namespace = "com.apple.QuartzComposer" | 335 nodes>: Patch with name "/units to pixels" is missing QuickTime Player[134] *** Message from <QCPatch = 0x06D82880 "(null)">:Cannot create node of class "/units to pixels" and identifier "(null)" QuickTime Player[134] *** Message from <QCPatch = 0x06D7C130 "(null)">:Cannot create node of class "/resize image to target" and identifier "(null)" QuickTime Player[134] *** Message from <QCPatch = 0x06D7C130 "(null)">:Cannot create connection from ["outputValue" @ "Math_1"] to ["Target_Pixels" @ "Patch_2"] The patch "units to pixels" is a system patch in Snow Leopard whereas the patch "resize image to target" is a custom virtual patch located in my home directory. It seems that we can cross out problems in which the composition is referencing a missing virtual patch. I have tested the composition under another user's account and it ran fine which shows that it already embeds the "resize image to target" virtual patch that is located in my home directory. I'm really puzzled why the composition passes the Leopard Runtime test but yet fail to run in an actual Leopard OS? Is there a post-processing step that I need to run to the composition file? Is there any way to make this patch more compatible with Leopard? Thanks in advance.

  • Django Upload form to S3 img and form validation

    - by citadelgrad
    I'm fairly new to both Django and Python. This is my first time using forms and upload files with django. I can get the uploads and saves to the database to work fine but it fails to valid email or check if the users selected a file to upload. I've spent a lot of time reading documentation trying to figure this out.

  • Prevent checkins to SVN

    - by Joseph Mastey
    My team uses SVN for our software platform, and we create tags periodically to help keep module versions straight. Best practice, as I understand it, is not to modify a tag once it has been created. However, it seems that sometimes the temptation is too great and a modification is made to one of the tags. Is there a way to prevent these kinds of checkins, or at least make them a complete pain so that we can discourage them automatically? Thanks, Joe
