数字图像处理，DFT，IDFT，DCT，IDCT，求频谱(Digital image processing, DFT, IDFT, DCT, IDCT, spectrum)

图片浏览源码例程，程序调用API函数实现图片的浏览。包括浏览文件夹对话框的“SHBrowseForFolderA”，以及配合它使用的从列表ID取路径“SHGetPathFromIDListA”(Picture Viewer source code routines , the program calls API functions for image browsing. )

改变图像灰度，增强图像中需要的信息，可利用与分割前处理(Change the image gray level, increase the information)

mean shift 均值漂移算法的matlab实现，大家可以看看，比较实用(mean shift algorithm matlab mean-shift realize, we can look at more practical)

对形图像的经过边缘提取后得到的二值图像边缘进行细化，提取单像素的边缘，使得边缘是成为清楚的单像素的边缘。(After images of the shape after the edge extraction of the binary image to refine the edge, the edge extraction of a single pixel, making the edge is to be clear of the edge of a single pixel.)

新发表论文Graph cuts based active contour model with selective local or global segmentation 附源码，基于图割的主动轮廓模型，用于有选择的局部分割或全局分割，欢迎下载！(Published Graph cuts based active the contour the model with selective local or global a segmentation attached source, the active contour model based on graph cuts for selected local partition or global segmentation are welcome to download!)

灰度差分统计法提取图像纹理特征，包括平均值，对比度，熵，等特征，matlab函数，直接接使用，无需修改，中文注释，通俗易懂(Gray difference statistical method is used to extract texture features of image, including mean value, contrast, entropy, etc., matlab function, directly used without modification, Chinese annotation, and easy to understand)

说明：  利用稀疏表示 omp k-svd训练字典的方法，实现了图像去噪(The sparse representation of OMP k-svd training dictionary is used to realize Image Denoising)

不均匀光照下的文字分割，综合运用同态滤波方法、Bernsen局部阈值法、边缘识别法。(Uneven illumination of the text segmentation, integrated use of homomorphic filtering methods, Bernsen local threshold, the edge identification method.)

图像重采样，根据新旧图像像元大小的比例进行图像的重采样，(This function resamples the images at the new grid points defined by the new pixel sizes. It assumes that intensities are defined at the pixel centers)
