Summary[edit]

Description
English: An example of a decomposition of an RGB image into colour and grey-scale components. The original RGB image is at the bottom. The top image is the colour component and the middle image is the grey-scale component. The original image can be reconstructed from the two components.

The colour component was obtained by setting V=1 (in the HSV colour model) for every pixel in the image. This maximises the luminance of every pixel while retaining the colour (hue + saturation) unchanged. Note: V = max(R,G,B).

The grey-scale component was obtained by setting the grey level for every pixel to a suitably weighted average of the R, G and B values at that pixel.

The original image was obtained from here.
