Screen Capture for subsequent Computer Vision Processing

What should I use to perform scr开发者_StackOverfloween capture on Windows for subsequent image processing?

I seek to do follow-up image processing in OpenCV.

Well the most straightforward thing to do is to use an off the shelf video capture tool to create an AVI file and then have image processing software operate on that, after the fact.

To get up and running:

• CamStudio is free and open source and has a simple gui.

• VirtualDub is also FOSS and is more powerful, but less intuitive to use. Its primarily a video editing and processing tool, but it actually has sophisiticated capture capabilities.

Both work on Windows and both can output uncompressed AVI files that OpenCV can read.

If you are completely new to OpenCV, then I recommend a O'Reilly's "Learning OpenCV". Its for the older OpenCV 1.1 but it will at least get you started.

If you crack open that book, and you find that its way above your head, then I would consider trying to do your image processing in a higher level language. MATLAB with the Image Processing Toolbox is well suited for rapid prototyping of image processing and its a much more forgiving development environment. Its an interpretative language, so you can see-as-you-code.

Based on the question as stated, this is as much info as I can provide. Perhaps consider providing more details about your specific application requirements?
