code for computing the entropy of gray scale image, including to calculate the local entropy (especially for matlab 7.0 and lower that dont have entropy and entropyfilt function)

基于纹理分析的图像分割，matlab开发，用entropyfilt，stdfilt等-Image segmentation based on texture analysis, matlab development, with entropyfilt, stdfilt etc.

WINDOWS操作系统下MATLAB图像处理工具箱，非常好用-Matlab demo-Image processing toolbox - Texture Segmentation Using Texture Filte (entropyfilt) - color-Based Segmentation Using K-Means Clustering Vgg-matlab Zisserman: Texture Classification: Are Filt
