Description: Normalises image values to 0-1, or to desired mean and variance
Usage:
n = normalise(im)
Offsets and rescales image so that the minimum value is 0
and the maximum value is 1. Result is returned in n. If the image is
colour the image is converted to HSV and the value/intensity component
is normalised to 0-1 before being converted back to RGB.

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 Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in {0, 1, ..., 255} into an RGB triple with real-valued components in [0,1]. RGB() allows the user to access a set of 21 colors via their common English names. For eight of these colors that have more than one common name, the program accepts alternative names, reducing the memory burden on the user.-The Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in {0, 1, ..., 255} into an RGB triple with real-valued components in [0,1].

Description: This function saves a figure or single axes to one or more vector and/or bitmap file formats, and/or outputs a rasterized version to the workspace, with the following properties:
- Figure/axes reproduced as it appears on screen
- Cropped borders
- Embedded fonts (vector formats)
- Improved line and grid line styles (vector formats)
- Anti-aliased graphics (bitmap formats)
- Transparent background supported (pdf, eps, png)
- Semi-transparent patch objects supported (png only)
- RGB, CMYK or grayscale output (CMYK only with pdf, eps, tiff)
- Optionally append to file (pdf only)
- Vector formats: pdf, eps
- Bitmap formats: png, tif, jpg, bmp, export to workspace
This function is especially suited to exporting figures for use in publications and presentations, because of the high quality and portability of media produced.-This function saves a figure or single axes to one or more vector and/or bitmap file formats, and/or outputs a rasterized version to the workspace, with the following properties:

Description: The provided Matlab functions demonstrate a simple method for training and testing a color detection system. In general, a color detection algorithm searches an image for pixels that have a specific color. In this demo the HSV color space has been used, instead of the RGB space. According to that model, H(ue) dimension represents the "color", S(aturation) dimension represents the dominance of that color and the V(alue) dimension represents the brightness. Therefore, the color detection algorithm can search in terms of color position and color "purity", instead of searching for specific RGB values. We have to note here, that in order to detect the desired color, it is needed to define a tolerance in each HSV dimension. For example a tolerance equal to 0.050 in the H dimension means that the algorithm will detect pixels whose H value has a distance (from the desired value) less than 0.050.
