Detailed Description

k-Means based color quantization.

This functor calculates (using k-Means) an optimal color subpalette for the input image. The maximal number of colors to be used is given through the parameters (inherited from colorQuantization::parameters).

If the real number of colors used in the image is less than the desired number of quantized colors, no quantization is done and the output palette will contain all image colors, i.e. it will be smaller that the expected size of parameters::numberOfColors.

Member Function Documentation

bool lti::kMColorQuantization::apply	(	const image &	src,
		image &	dest
	)			const `[virtual]`

Operates on the given parameter.

Parameters:

	src	image with the source data.
	dest	image with only the number of colors specified in the parameters

Returns:: true if apply successful or false otherwise.

Reimplemented from lti::colorQuantization.

bool lti::kMColorQuantization::apply ( image & srcdest ) const [virtual]

Operates on the given parameter.

Parameters:

srcdest

image with the source data. The result will be left here too.

Returns:: true if apply successful or false otherwise.

Reimplemented from lti::colorQuantization.

bool lti::kMColorQuantization::apply	(	const image &	src,
		channel8 &	dest,
		palette &	thePalette
	)			const `[virtual]`

Apply.

Operates on a copy of the given parameters.

Parameters:

	src	original image with the true-color data
	dest	channel8 where the indexes of the also calculated palette will be.
	thePalette	the color palette used by the channel. If it is not empty, it will be taken as a InitPalette for the computation of the new one.

Returns:: true if apply successful or false otherwise.

Implements lti::colorQuantization.

bool lti::kMColorQuantization::apply	(	const image &	src,
		matrix< int > &	dest,
		palette &	thePalette
	)			const

Apply.

Parameters:

	src	original image with the true-color data
	dest	matrix<int> where the indexes of the calculated palette will be.
	thePalette	the color palette used by the matrix. If it is not empty, it will be taken as a InitPalette for the computation of the new one.
