在伦敦大学学院的CVRL 实验室官网下载: CIE 1931 2-deg, XYZ CMFs CIE 1931 2-deg xyz chromaticity coordinates 第一样是 CIE 1931 XYZ 颜色匹配函数(Color Matching Function, CMF),第二样是 CMF 的色度坐标,范围从 360 到 830 nm,分辨率为 1nm。 构造网格 人眼可见色域落在 xy 平面上的x,y∈[0,1...
从事CMF,必绕不开色彩;要说色彩,就得讲讲色彩学;而要讲色彩学,作为现代色度学基石的大杀器——CIE色度图,是一定绕不过去的。不过这个色度图,一直让很多人头疼,不知道该怎么理解。很多资料也是浅尝则止。这也难怪,因为CIE色度图里的确有很多技术细节,三言两语说不清楚。 今天我们就来完成这个艰巨的任务,把它从...

Further, CIE mathematically put all the luminance data into one of the primaries to simplify the rest. This resulted in thealychne, or the line of “no light”, shown below. We can see that the alychne starts at 0,0, and has a slope of -0.2/1.0. Meaning that there is no energy...

The corresponding graphical results are called the color-matching functions (CMF). The interpretation of these graphs is that they show how much of each primary (called the tristimulus value) is needed to match unit of intensity of a single wavelength of light. Following example shows how color...
