Decolorization

decolor

Transforms a color image to a grayscale image. It is a basic tool in digital printing, stylized black-and-white photograph rendering, and in many single channel image processing applications [CL12].

C++: void decolor(InputArray src, OutputArray grayscale, OutputArray color_boost)

Parameters:

• src – Input 8-bit 3-channel image.
• grayscale – Output 8-bit 1-channel image.
• color_boost – Output 8-bit 3-channel image.

This function is to be applied on color images.
