Separate color channelsπ
Separates a color image to components, each represented by a gray-level image. To combine color channels back to a color image, use color combining.
Inputsπ
image
: A color image. If a gray-level input image is received, it will be sent to all three outputs as such.channel0Enabled
: If set totrue
, channel0 output will be generated.channel1Enabled
: If set totrue
, channel1 output will be generated.channel2Enabled
: If set totrue
, channel2 output will be generated.channel3Enabled
: If set totrue
, channel3 output will be generated.
Outputsπ
channel0
: The first color channel as a gray-level image. If the input is an RGB image, this will be the red color channel.channel1
: The second color channel as a gray-level image (green in the case of an RGB image).channel2
: The third color channel as a gray-level image (blue in the case of an RGB image).channel3
: The fourth color channel as a gray-level image. Most color images donβt have a fourth color channel, but it can be used for storing additional information in some applications. A typical use is to store opacity (alpha) with RGB.
