Channel

Channel operations allow extracting or merging the channels (bands) of color images.

Extraction

When the input image is a color image, this function allows extracting one channel (using the RGB or IHS color space) or transforming a color image into a Real Gray image (see Color image).

Merging

Allows creating a color image in the RGB or IHS space by selecting 3 channels of any image.

RGB:

Channel 1 -> Red

Channel 2 -> Green

Channel 3 -> Blue

IHS:

Channel 1 -> Intensity

Channel 2 -> Hue

Channel 3 -> Saturation
