Member Function Documentation

virtual functor::parameters* lti::watershedSegmentation::parameters::clone

(

)

const [virtual]

returns a pointer to a clone of the parameters

Reimplemented from lti::segmentation::parameters.

parameters& lti::watershedSegmentation::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::watershedSegmentation::parameters::getTypeName

(

)

const [virtual]

returns name of this type

Reimplemented from lti::segmentation::parameters.

parameters& lti::watershedSegmentation::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::watershedSegmentation::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::segmentation::parameters.

virtual bool lti::watershedSegmentation::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

int lti::watershedSegmentation::parameters::basinValue

gray value to be used for basins in the resulting channel8

bool lti::watershedSegmentation::parameters::neighborhood8

defines the neighborhood of a pixel.

if set to false (default), only the pixels horizontally and vertically bordering are considered to be neighbors.

if set to true, the four diagonally adjoining pixels are also taken into account.

bool lti::watershedSegmentation::parameters::rainfall

Rainfalling Watersheds or Standard-Waterfall.

Default: true (Rainfall-Watersheds, they are much faster)

ubyte lti::watershedSegmentation::parameters::threshold

Threshold to eliminate noise in the src-image.

Default value: 0

To avoid oversegmentation, try higher values (for example 4). Another usual measure to reduce oversegmentation is also to denoise the input image, using median-filters, SUSAN denoiser or mean-shift denoisers, among many other possibilities.

int lti::watershedSegmentation::parameters::watershedValue

gray value to be used for watersheds in the resulting channel8
