matlab数学应用工具箱，里面附有各种应用范例。(Applied mathematics matlab toolbox, which accompanied by examples of a wide range of applications.)

I wrote this program for coloring any map with only 4 colors. Input for it is an bitmap file with 24 bit colors (must gray/scale). Output is a bitmap which is colored with maximum 4 colors.

说明：  guass法解矩阵的源程序，编的水平有限，仅供参考(guass method solution matrix of the source, compiled is limited, for reference only)

无参考的图像质量评价算法，基于图像的空域与频域的信息熵，超过现存的所有质量评价算法。(No reference image quality uation algorithm, and information based on spatial frequency domain of the image entropy over all existing quality uation algorithm.)
