基于各向异性扩散的医学图像的边缘检测与分割处理(Based on the anisotropic diffusion of medical image segmentation and edge detection)

这个matlab程序是基于纹理的图像检索源码，纹理特征是图像的基本特征特征之一，所以基于纹理的图像检索是图像处理的热点。(The matlab program is based on the source texture image retrieval, texture image is characterized by one of the characteristics of the basic features, so texture-based image retrieval is a hot image processing.)

基于样本的纹理合成加速方法，MRF，基于Li-Yi Wei的论文。(Acceleration method based on texture synthesis samples, MRF, based on Li-Yi Wei of paper.)

图像处理,matlab文件，利用SURF进行图像拼接，完成图像配准(Image processing, matlab files, image stitching using SURF, image registration completed)

sift 图像特征提取算法源码，对研究sift算法很有帮助。(The source code of sift image feature extraction algorithm is very helpful to the research of sift algorithm.)

Retinex算法本质上就是一种基于光照补偿的图像增强算法, 能够对高动态范围图像进行增强。(Retinex algorithm is essentially an image enhancement algorithm based on illumination compensation, which can enhance the image of high dynamic range.)
