template<typename T >
bool AddFeatures (std::map< int, T > &container, int type_id=0, int first_id=0, int last_id=65535)
 add features to the previously tracked frame if there are less than min_features
bool DelFeature (int index)
 Stop tracking the identified feature (with index for features array)
bool DelFeatureId (int id)
 Stop tracking the identified feature (with feature id)
template<typename T >
int EraseNonTracked (std::map< int, T > &container, int type_id=-1)
 Erases the items matching with type_id having has_p2d == false . If type_id == -1 doesn't test the type.
void Purge ()
 Purge features that are considerably closer than the defined min_distance.
void Reset ()
 Reset.
double Reset (IplImage *img, IplImage *mask)
 Reset track features on specified mask area.
template<typename T >
bool Track (IplImage *img, IplImage *mask, std::map< int, T > &container, int type_id=-1, int first_id=-1, int last_id=-1)
 Track features with matching type id. New features will have id's in the specified id range.

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
