从网络摄像头拍摄的照片上的形状识别

Question

i would like to extract information is there a human hand on some photo taken from local webcam. I get how to extract light information, find brightest points or few of them, but how to recognize shape on some image?

I have started C# project, and I'm using AForge library to apply some filters to captured images, but I'm pretty stuck with shape recognition.

Where should I start?

Answer 1

You might have a look at the image recognition project over at codeplex.

http://www.codeplex.com/IR

It is an open source .NET project written in c#. It should be a good place to start.

Answer 2

You can do this with OpenCV , using haar cascades.

There's even a classifier readily available for non-commercial use - see http://code.google.com/p/ehci/wiki/HandTracking
