Detailed Description

Visualize a label mask in a color image.

This class draws a color image using as input a labeled mask. The colors used for each label are chosen based on the adjacency, so that two neighbor labels never get the same color.

You can choose the kind of neighborhood used (4 or 8 neighborhood) and the number of colors you want to use.

Other classes, like the viewers, may require partial computations, like the adjacency graph, which is a kind of

Member Function Documentation

bool cvr::labelAdjacencyMap::adjacency	(	const matrix< int > &	mask,
		graph &	dest
	)			const

Compute the adjacency graph of labels for the given labeled mask.

bool cvr::labelAdjacencyMap::adjacency	(	const matrix< ubyte > &	mask,
		graph &	dest
	)			const

Compute the adjacency graph of labels for the given labeled mask.

bool cvr::labelAdjacencyMap::apply	(	const matrix< int > &	src,
		image &	dest
	)			const

Compute the adjacency map of the given 32-bit labeled mask.

The input data cannot have label ids less than zero and internally a look-up table of the size equal to the maximum value in the input data plus one will be created. So, it will be assumed that the input mask has all its labels with low positive ids.

Parameters:

	src	matrix<int> with the source data.
	dest	image where the result will be left.

Returns:

true if apply successful or false otherwise.

bool cvr::labelAdjacencyMap::apply	(	const matrix< ubyte > &	src,
		image &	dest
	)			const

Compute the adjacency map of the given 8-bit labeled mask.

Parameters:

	src	channel8 with the source data.
	dest	image where the result will be left.

Returns:

true if apply successful or false otherwise.

virtual labelAdjacencyMap* cvr::labelAdjacencyMap::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements cvr::functor.

bool cvr::labelAdjacencyMap::computeMaxPalette	(	const graph &	adj,
		ivector &	pal
	)			const [protected]

Compute a transformation Look-up Table that maps the id of a label to the corresponding entry in the parameters palette.

The maximum number of colors will be used.

bool cvr::labelAdjacencyMap::computeMaxPalette	(	const graph &	adj,
		palette &	pal
	)			const [protected]

Compute a "palette" from the graph, which can be accessed with the id of a label to get the corresponding color in the map.

The maximum number of colors will be used.

bool cvr::labelAdjacencyMap::computeMinPalette	(	const graph &	adj,
		ivector &	pal
	)			const [protected]

Compute a transformation Look-up Table that maps the id of a label to the corresponding entry in the parameters palette.

The minimum number of colors will be used.

bool cvr::labelAdjacencyMap::computeMinPalette	(	const graph &	adj,
		palette &	pal
	)			const [protected]

Compute a "palette" from the graph, which can be accessed with the id of a label to get the corresponding color in the map.

The minimum number of colors will be used.

bool cvr::labelAdjacencyMap::computePalette	(	const graph &	adj,
		ivector &	pal
	)			const

Compute a transformation Look-up Table that maps the id of a label to the corresponding entry in the parameters palette.

bool cvr::labelAdjacencyMap::computePalette	(	const graph &	adj,
		palette &	pal
	)			const

Compute a transformation Look-up Table that maps the id of a label to the corresponding entry in the parameters palette.
