リンク 翻訳 Hi, if you have the Image Processing Toolbox available, use the function makecform (with parameter 'xyz2lab'). Otherwise: take a look e.g. athttp://brucelindbloom.com/where the formulae are given. It's straigt forward to implement in MATLAB. ...
Tests based on hue linearity and ellipse datasets show that MLAB color space is also improved to a certain extent compared with CIELAB color space. 1 引言色度学将三刺激值XYZ空间作为基础的颜色空间。根据应用场景的不同,研究人员着力于将三刺激值空间转换为其他空间,如用于色差计算和色彩分析的CIELAB...

(2) Items ending in a digit (usually zero) are experimental; they are released to allow widespread testing, but are guaranteed to be broken in future (if only by dropping the zero). By all means play with these and give feedback, but do not use them in production scripts. Package ...
