• What is the best way to detect white color?

  - by dnul

  I'm trying to detect white objects in a video. The first step is to filter the image so that it leaves only white-color pixels. My first approach was using HSV color space and then checking for high level of VAL channel. Here is the code: //convert image to hsv cvCvtColor( src, hsv, CV_BGR2HSV ); cvCvtPixToPlane( hsv, h_plane, s_plane, v_plane,…

• Flash SWF not initializing until visible - can I force them to initialize?

  - by Jason

  I have an application that needs to render about 100 flash graphs (as well as other DOM stuff) in a series of rows that vertically extend many times beyond the current visible window - in other words, the users have to scroll down see see all the different graphs. This application is also dynamic and when a user changes a value in the DOM…

• Resizing a GLJPanel with JOGL causes my model to disappear.

  - by badcodenotreat

  I switched over to using a GLJPanel from a GLCanvas to avoid certain flickering issues, however this has created several unintended consequences of it's own. From what I've gleaned so far, GLJPanel calls GLEventListener.init() every time it's resized which either resets various openGL functions i've enabled in init() (depth test,…

  Hi Guys, I'm trying to learn OpenGL ES quickly (I know, I know, but these are the pressures that have been thrusted upon me) and I have been read around a fair bit, which lots of success at rendering basic models, some basic lighting and 'some' texturing success too. But this is CONSTANTLY the point at which all OpenGL ES…

• Determining if an unordered vector<T> has all unique elements

  - by Hooked

  Profiling my cpu-bound code has suggested I that spend a long time checking to see if a container contains completely unique elements. Assuming that I have some large container of unsorted elements (with < and = defined), I have two ideas on how this might be done: The first using a set: template <class T> bool…

• How do you use glFrustrum in OpenGL ES1 on iPhone

  - by Paul

  So I am using Xcode 3.2.1 and am trying to make an iPhone OpenGL ES1 project.
