Color extraction Color convertion
Extracts specific color components from color image.
Specification of color components can be selected from "red", "green", "blue"and
"manual".
Taking an orange's image as an example, When extracting (red), the brightness
becomes large, and when extracting with (blue), the brightness becomes small.
When extracting with an arbitrary color, specify it in the range of 0 to 360 ° from H
(hue) in the HSV color space.
