There is a really cool (At least I think it is) Image Processing Library (Tiger Imaging) for C# here (Code Project). It comes with complete source code and provides some really cool filters that enable you to perform a bit of image manipluation easily. It is by a guy called Andrew Kirillov and he has another article on the code project here where he demonstrates Montion Capture using his library.I am just wondering if I should create some filters (such as fish eye that Jason Waltman describes). I have some plans for doing a bit of research with Tiger Imaging....
