I am using Opencv face detection but its both speed and performance are not satisfactor and now I am planning to use Intel IPP Face detection. Would you please tell me the major difference between Opencv Face Detection and the Intel IPP Face Detection? Also, in IPP, there is another haar cascades. Is it possible to use our own cascade or Intel has another haar training utility?
Did you notice that OpenCV (especially the latest version 1.1) can benefit from IPP when IPP DLL are available onthe system? IPP use compatible haar cascades the difference might be in file format which may change in the latest versions of OpenCV.
You also may want to take a look on IPP picnic application sample to see how to use IPP face detection functions.
