Yes, I know there are unresolved issues wrt to representing polar coordinates in `color()` and we'd need to solve these first. Maybe by changing its grammar to be `[ | | none]+` instead of `[ | none]…

您好，我不了解lab的范围是怎么定下来的？
您使用的是color.rgb2lab 得到的lab的界限好像是l属于0~100，a和b属于-128~127
但是还有的代码是用的cv2换的颜色空间，cv2默认把l,a,b都归一化到了0~255
但是论文中又没有提到这个问题，请问你是怎么理解的呢
