Member Function Documentation

Purge()

void Purge ( )

inline

Purge features that are considerably closer than the defined min_distance.

Note, that we always try to maintain the smaller id's assuming that they are older ones

Definition at line 464 of file EC.h.

Track()

bool Track ( cv::Mat &  img, cv::Mat &  mask, std::map< int, T > &  container, F  do_handle_test, int  type_id = 0, int  first_id = -1, int  last_id = -1  )

inline

Track features matching the given functor. New features will have id's in the specified id range.

Track features matching the given functor. If first_id >= 0 we call AddFeatures with the specified id range.
