	Stop tracking the identified feature (with index for features array)

	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.

		int	last_id = 65535
	)		[inline]

add features to the previously tracked frame if there are less than min_features

bool alvar::TrackerFeaturesEC::DelFeature

(

int

index

)

[inline]

Stop tracking the identified feature (with index for features array)

Reimplemented from alvar::TrackerFeatures.

Definition at line 387 of file EC.h.

bool alvar::TrackerFeaturesEC::DelFeatureId

(

int

id

)

[inline]

Stop tracking the identified feature (with feature id)

Reimplemented from alvar::TrackerFeatures.

Definition at line 388 of file EC.h.

template<typename T >

int alvar::TrackerFeaturesEC::EraseNonTracked	(	std::map< int, T > &	container,
		int	type_id = -1
	)		[inline]

Erases the items matching with type_id having has_p2d == false . If type_id == -1 doesn't test the type.

Definition at line 375 of file EC.h.

void alvar::TrackerFeaturesEC::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

Reimplemented from alvar::TrackerFeatures.

Definition at line 384 of file EC.h.

void alvar::TrackerFeaturesEC::Reset

(

)

[inline]

Reset.

Reimplemented from alvar::TrackerFeatures.

Definition at line 385 of file EC.h.

double alvar::TrackerFeaturesEC::Reset	(	IplImage *	img,
		IplImage *	mask
	)		[inline]

Reset track features on specified mask area.

Reimplemented from alvar::TrackerFeatures.

Definition at line 386 of file EC.h.

template<typename T >

bool alvar::TrackerFeaturesEC::Track	(	IplImage *	img,
		IplImage *	mask,
		std::map< int, T > &	container,
		int	type_id = -1,
		int	first_id = -1,
		int	last_id = -1
	)		[inline]

Track features with matching type id. New features will have id's in the specified id range.

Definition at line 262 of file EC.h.

template<typename T , typename F >

bool alvar::TrackerFeaturesEC::Track	(	IplImage *	img,
		IplImage *	mask,

		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.
