Here experiments with the Open Source Computer Vision Library (OpenCV) have been carried out. A part of the library, that is sufficient for an application using the Canny edge detector, has been compiled for Windows CE. The necessary steps to compile this part with eMbedded Visual C++ 4.0 you can find on this page. Here is the sample application.
Have you compiled a part or the entire library for Windows CE? If you want to volunteer your experience, send a message please.
