Detailed Description

Weight pixel values of all image channels.

Pixels of all channels in source image are weighted by a channel-wise weight:

$D(x,y,c) = S(x,y,c)*w(c)$

where $D$ is the destination image, $S$ is the source image, $w$ is the weight vector and $C$ is the source images channel count.

Performance: 1000x1000 image with 10 channels averaged over 100 runs (1,83 GHz Core Duo)

Performance: 1000x1000 image with 3 channels averaged over 100 runs (1,83 GHz Core Duo)

Constructor & Destructor Documentation

icl::filter::WeightChannelsOp::WeightChannelsOp ( ) [inline]

creates a new WeightChannelsOp object

icl::filter::WeightChannelsOp::WeightChannelsOp ( const std::vector< icl64f > & weights ) [inline]

creates an new WeightChannelsOp object with a given weights vector

Parameters:

weights channel weights vector

void icl::filter::WeightChannelsOp::apply	(	const core::ImgBase *	poSrc,
		core::ImgBase **	ppoDst
	)		`[virtual]`

applies this operation on the source image

Parameters:

poSrc	source image
ppoDst	destination image (adapted to icl32f by default, if the source image has depth64f, ppoDst is adapted to icl64f too.

const std::vector<icl64f>& icl::filter::WeightChannelsOp::getWeights ( ) const [inline]

returns the current weight vector

void icl::filter::WeightChannelsOp::setWeights ( const std::vector< icl64f > & weights ) [inline]

sets up the current weights vector

Parameters:

weights new weight vector

internal storage for the channel weights
