Description: 该程序首先把rgb图像转化为XYZ空间，然后在XYZ空间进行一些阈值找到黄色的底色车牌，这是从国外的车牌识别程序，但不明白那些阈值为什么要那么设，用的是什么原理？
还有一个疑问就是，这个程序对于输入的车牌有时候找到的是车牌的底，有时候是车牌的数字。一个是黄色，一个是白色。真不知道怎么找的。-The program first rgb image into XYZ space, and then in the XYZ space to some threshold to find a yellow background plates, this is from a foreign license plate recognition program, but those who do not understand why the threshold then set up, using the What is the principle? There is also a doubt is that this procedure for the importation of the license plate is sometimes found at the end of license plates, and sometimes the number of plates. One is yellow, one is white. Really do not know how to find.

Description: RGB,YCbCr,HSV,HSL,CIE等颜色空间转换
这个Matlab程序用于颜色空间的转换。可以在RGB, YPbPr, YCbCr, YUV, YIQ, YDbDr, JPEG-YCbCr, HSV, HSL, XYZ, CIE Lab (CIELAB), CIE Luv (CIELUV), and CIE Lch (CIELCH)等颜色空间中任意转换。-B = colorspace( dest<-src , A) converts image A from color space src to color space dest .
Example:
B = colorspace( HSV<-RGB ,A) Convert image A from RGB to HSV
C = colorspace( YCbCr<-HSV ,B) Convert HSV to YCbCr
D = colorspace( RGB<-YCbCr ,C) Convert YCbCr back to RGB

Description: The main purpose of the core is a color transform tasks such as CIE XYZ<->RGB, different RGB<->RGB and RGB<->YCbCr operations. The main part of color conversions from one to another color system concludes in 3x3 matrix multiplication with vector addition. Therefore the present core performs true 3x3 matrix multiplication and vectors addition of the input data stream.
In the package ccfactors_pkg.vhd presents matrixes for all of the most popular conversions. You can use these defines or type own factors.
Input DATA_WIDTH is changeable and defines by the GENERIC param of the module. Precision of the matrix factors also is changeable. Default precision – 10-E6. Better than enough for color conversion tasks.

Description: matlab写的 处理图片白平衡的三种方法
第一种，选取图片中最亮的点作为white
第二种，手动选取任一点作为white
第三种，求RGB的平均作为white
其中包含了rgb xyz等空间转换代码，有CAT02， 和VK chromatic adaptation transforms
适合颜色科学相关专业-1. the brightest object in the imge is just white.
2. select a white object from the image
3. assume the average color data of the image is just a medium gray, get the white from this.
others: the color space transform, RGB to XYZ, the chromatic adaptation transform code: cat02, VK.
A 2nd level of color science.
