本文介绍了几种常用的颜色空间，包括RGB、HSV、HLS、YCrCb和CIEL*a*b*。这些颜色空间各有特点，如RGB最常见，HSV和HLS更符合人类对颜色的感知，YCrCb被广泛应用于JPEG格式，而CIEL*a*b*则在测量颜色距离方面非常有用。

                    
                    RGB is the most common as our eyes use something similar, but keep in mind that the OpenCV display system uses BGR colors.
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 value component, making your algorithm less sensitive to the light conditions of the input image.
YCrCb is used by the popular JPEG 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.
