Detailed Description

template<class ConverterT, class AngleT>
class CvFaceTrack< ConverterT, AngleT >

CvFaceTrack tracks the faces in the video stream durig non-detection frames. NOTE: this class can be replaced by OmniTracking class. Some changes should be done on CvFaceDetect too to accomplish the point to add structures..
