Windows CE OpenCV performance

Im using OpenCV on Windows CE 6.0 R2 on and the performance is quite weak. I can do 300 YUV to RGB conversions per second开发者_StackOverflow中文版 (using my code), but OpenCV takes 3 seconds to perform a single cvGoodFeaturesToTrack() on a VGA image. I know OpenCV uses STL a lot, does anyone have experience with STL on Windows CE?

Thanks, Filip

cvGoodFeaturesToTrack() is a heavy function that uses a lot of floating point operations. If your platform does not support FP ops that would explain what your are seeing.
Try using the FAST features which are, well, FAST.
