Member Function Documentation

virtual functor::parameters* lti::coilBackgroundSegmentation::parameters::clone

(

)

const [virtual]

returns a pointer to a clone of the parameters

Reimplemented from lti::segmentation::parameters.

parameters& lti::coilBackgroundSegmentation::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::segmentation::parameters.

const char* lti::coilBackgroundSegmentation::parameters::getTypeName

(

)

const [virtual]

returns name of this type

Reimplemented from lti::segmentation::parameters.

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

read the parameters from 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::segmentation::parameters.

virtual bool lti::coilBackgroundSegmentation::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::segmentation::parameters.

Member Data Documentation

dmatrix lti::coilBackgroundSegmentation::parameters::covarMatrixBackground

The size and shape of the additional covariace matrix.

Only affecting the result if meanBackgroundColor >= 0. (See also: meanBackgroundColor)

Default value: 100 on the main diagonal, 0 otherwise

int lti::coilBackgroundSegmentation::parameters::iterations

The number of iterations the object- and background-masks take to grow outside and inside the object.

Default value: 10

float lti::coilBackgroundSegmentation::parameters::maskFactor

The factor the first object- and background-mask is stretchend.

Values > 1 should be used if the image is larger than 128*128 pixels in order to get a sharper segmentation around the object.

Minimum value: 1 Default value: 1

int lti::coilBackgroundSegmentation::parameters::maxNumberBestOfN

The number of masks created.

From them the final mask will be generated with the value zero where not all masks were nonzero. 4 is enough for a good result, but values >= 100 will generate the best possible solution (high values will cause a long time to do the segmentation).

Minimum value: 2 Default value: 100

int lti::coilBackgroundSegmentation::parameters::meanBackgroundColor

The mean background color to be expected in order to improve results by estimating with another covariance matrix.

If the backgroundcolor is unknown use meanBackgroundColor = -1 to disable. Otherwise use only values between 0 and 255. (See also: covarMatrixBackground.)

Default value: 0 (black)

double lti::coilBackgroundSegmentation::parameters::thresholdFactor

The factor the threshold decinding between object and background is stretched.

Lower values will cause better results with objects containing many dark spots. Higher values prevent 'noise' outside the object.

Default value: 1.30
