Detailed Description

Color quantization functor based on the local k-Means algorithm of O.

Verevka and J. W. Buchanan (see original paper here).

The modifications are basically in the use of a LUT for the computation of the L2 norm, which makes the algorithm as efficient as using the originally proposed L(1/2) norm and the consideration of a direct neighbourhood to avoid some problems with simple quantization problems.

Member Function Documentation

bool lti::lkmColorQuantization::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::lkmColorQuantization::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::lkmColorQuantization::apply	(	const image &	src,
		channel8 &	dest,
		lti::palette &	lkmCPalette
	)			const [virtual]

operates on a copy of the given parameters.

Parameters:

	src	image with the source data.
	dest	image where the result will be left.
	lkmCPalette	the color palette with the quantized colors

Returns:

true if apply successful or false otherwise.

Implements lti::colorQuantization.

virtual functor* lti::lkmColorQuantization::clone
