Description: ％ function [L, a, b] = RGB2Lab(R, G, B)
％ RGB2Lab takes matrices corresponding to Red, Green, and Blue, and
％ transforms them into CIELab. This transform is based on ITU-R
％ Recommendation BT.709 using the D65 white point reference.
％ The error in transforming RGB -> Lab -> RGB is approximately
％ 10^-5. RGB values can be either between 0 and 1 or between 0 and 255.
％ By Mark Ruzon from C code by Yossi Rubner, 23 September 1997.

Description: Convert a color image between color representations.
B = COLORSPACE(S,A) converts the color representation of image A
where S is a string specifying the conversion. S tells the
source and destination color spaces, S = dest<-src , or
alternatively, S = src->dest . Supported color spaces are
RGB R G B Red Green Blue (ITU-R BT.709 gamma-corrected)
YPbPr Luma (ITU-R BT.601) + Chroma
YCbCr / YCC Luma + Chroma ("digitized" version of Y PbPr)
YUV NTSC PAL Y UV Luma + Chroma
YIQ NTSC Y IQ Luma + Chroma
YDbDr SECAM Y DbDr Luma + Chroma
JPEGYCbCr JPEG-Y CbCr Luma + Chroma
HSV / HSB Hue Saturation Value/Brightness
HSL / HLS / HSI Hue Saturation Luminance/Intensity
XYZ CIE XYZ
Lab CIE L*a*b* (CIELAB)
Luv CIE L*u*v* (CIELUV)
Lch CIE L*ch (CIELCH)-Convert a color image between color representations. B = COLORSPACE (S, A) converts the color representation of image A where S is a string specifying the conversion.

Description: For images with color, it seems obvious that an additional term must be added to consider the difference between the color of the background and the color of the target. In other words, if at present the contrast between the target and the background is an "intensity" contrast, the new contrast should contain a term including the "color" contrast.-For images with color, it seems obvious that an additional term must be added to consider the difference between the color of the background and the color of the target.

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
