Detailed Description

the parameters for the class lkTracker

Constructor & Destructor Documentation

lti::lkTracker::parameters::parameters ( )

default constructor

Reimplemented from lti::modifier::parameters.

lti::lkTracker::parameters::parameters ( const parameters & other )

copy constructor

Parameters:

other

the parameters object to be copied

Reimplemented from lti::modifier::parameters.

lti::lkTracker::parameters::~parameters ( ) [virtual]

destructor

Reimplemented from lti::functor::parameters.

Member Function Documentation

virtual functor::parameters* lti::lkTracker::parameters::clone ( ) const [virtual]

returns a pointer to a clone of the parameters

Reimplemented from lti::modifier::parameters.

parameters& lti::lkTracker::parameters::copy ( const parameters & other )

copy the contents of a parameters object

Parameters:

other

the parameters object to be copied

Returns:: a reference to this parameters object

Reimplemented from lti::modifier::parameters.

const cornerDetector& lti::lkTracker::parameters::getCornerDetector ( ) const

get a read only reference to the corner detector object being used

cornerDetector& lti::lkTracker::parameters::getCornerDetector ( )

get a reference to the corner detector functor being used

const char* lti::lkTracker::parameters::getTypeName ( ) const [virtual]

returns name of this type

Reimplemented from lti::modifier::parameters.

parameters& lti::lkTracker::parameters::operator= ( const parameters & other )

copy the contents of a parameters object

Parameters:

other

the parameters object to be copied

Returns:: a reference to this parameters object

virtual bool lti::lkTracker::parameters::read	(	ioHandler &	handler,
		const bool	complete = `true`
	)			`[virtual]`

write the parameters in the given ioHandler

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:: true if write was successful

Reimplemented from lti::modifier::parameters.

bool lti::lkTracker::parameters::setCornerDetector ( const cornerDetector & cdet )

set the corner detector to be used.

A copy of the given functor will be made.

virtual bool lti::lkTracker::parameters::write	(	ioHandler &	handler,
		const bool	complete = `true`
	)			const `[virtual]`

write the parameters in the given ioHandler

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:: true if write was successful

Reimplemented from lti::modifier::parameters.

Member Data Documentation

bool lti::lkTracker::parameters::autoCorners

if true, a corner detector is used.

Default is true

cornerDetector* lti::lkTracker::parameters::cornerFinder [protected]

cornerDetector used to generate the corners.

Default value:

float lti::lkTracker::parameters::errorThreshold

if the difference between both matched windows is greater than this threshold, the point will be marked as invalid, and it will not be tracked any more.

Default value: 0.99f

float lti::lkTracker::parameters::eta2Threshold

This is the square of the computed pixel residual which must be reached before the algorithm stops.

Default value: 0.0009f (0.03*0.03);

int lti::lkTracker::parameters::maxStepsPerLevel

maximal number of iteration steps per pyramid level.

Default value: 10

int lti::lkTracker::parameters::numLevels

NumLevels gives the number of levels in the Pyramid.

Default value is 4

int lti::lkTracker::parameters::windowSize

WindowSize gives the size of the window used for comparsion of the features.
