详细的matlab图像处理，有DCT变换图像压缩，对比度增强，直方图均衡化，规定化，平滑滤波，锐化，频域滤波等-Detailed matlab image processing, image compression with DCT transform, contrast enhancement, histogram equalization, the provisions of, smoothing, sharpening, frequency domain filtering

本代码是程明明2011发表的文章 基于全局对比度的显著性区域检测，其中HC部分的matlab 实现代码，经本人测试，证明有效。-this code is for Global Contrast based Salient Region Detection（CVPR2011）,Histogram Contrast.
