Detailed Description

Accumulate weighted pixel values of all image channels.

Pixels of all channels in source image are weighted by a channel-wise weight and accumulated to the destination image:

$D(x,y,0) = \sum\limits_{c=0}^C S(x,y,c)*w(c)$

where $D$ is the destination image, $S$ is the source image, $w$ is the weights vector and $C$ is the source images channel count. The result image is created with depth32f by default. Only if the source image has a 64Bit floating point depth (depth64f), the destination image is adapted to depth64f to avoid loss of precession.

Performance: 1000x1000 image with 10 channels (1400Mhz Centrino)

icl8u: 82ms
icl32f: 96ms
icl64f: 170ms

Performance: 1000x1000 image with 3 channels (1400Mhz Centrino)

icl8u: 21ms
icl32f: 25ms
icl64f: 47ms
