Member Function Documentation

virtual functor::parameters* lti::gHoughTransform::parameters::clone

(

)

const [virtual]

returns a pointer to a clone of the parameters

Reimplemented from lti::modifier::parameters.

parameters& lti::gHoughTransform::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 char* lti::gHoughTransform::parameters::getTypeName

(

)

const [virtual]

returns name of this type

Reimplemented from lti::modifier::parameters.

parameters& lti::gHoughTransform::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::gHoughTransform::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.

virtual bool lti::gHoughTransform::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

int lti::gHoughTransform::parameters::disRotation

size of forth dimension of parameter-space discretisation of paramter rotation

int lti::gHoughTransform::parameters::disSize

size of third dimension of parameter-space discretisation of parameter size

float lti::gHoughTransform::parameters::extension

range of object-extension which is considered

bool lti::gHoughTransform::parameters::findLocalMaximum

true: search for local maxima (is very computational intensive) false: search for global maxima (is faster and default)

int lti::gHoughTransform::parameters::kernelSizeRotation

kernelSizeRotation is size of environment which is considered in search for local maxima at each position in parameter-space for rotation.

Default: 21

int lti::gHoughTransform::parameters::kernelSizeScale

kernelSizeSize is size of environment which is considered in search for local maxima at each position in parameter-space for size

Default: 11

int lti::gHoughTransform::parameters::kernelSizeTranslation

kernelSize is size of environment which is considered in search for local maxima at each position in parameter-space for row and column.

Default: 11

int lti::gHoughTransform::parameters::numberOfAngleLists

Number of lists regarded for each pixel symmetrical to its orientation angle phi.

High values gain better result but more computational intensive.

int lti::gHoughTransform::parameters::numberOfObjects

number of Objects to be found (default 1)

float lti::gHoughTransform::parameters::thresholdEdgePixel

Values above thresholdEdgePixel are considered as pixel of edges and transformed into parameter space.

Best to use previously an edge detector e.g. susanEdges.

default 0.9

float lti::gHoughTransform::parameters::thresholdLocalMaximum

Local maxima of parameter-space with values above thresholdLocalMaximum are considered as found objects in image-space.

Values depend on number of pixels in image. Higher values fasten the search for maxima.

Default:10
