Color Space In OpenCV
There are, however, many other color systems each with their own advantages:
- RGB is the most common as our eyes use something similar, our display systems also compose colors using these.
- The HSV and HLS decompose colors into their hue, saturation and value/luminance components, which is a more natural way for us to describe colors. You might, for example, dismiss the last component, making your algorithm less sensible to the light conditions of the input image.
- YCrCb is used by the popular JPEG image format.
- CIE L*a*b* is a perceptually uniform color space, which comes handy if you need to measure the distance of a given color to another color.
