各种图像处理技术举例。其中原代码可以直接使用，非常不错。(various image processing technology, for example. The original code which can be used directly, very good.)

说明：  基于分水岭算法和图论的图像分割，所使用的方法为分水岭算法和Normalized Cut方法(Based on watershed algorithm and graph theory, image segmentation, the method used as a watershed algorithm and Normalized Cut method)

说明：  用于显著性检测的对比算法SP的MATLAB版本，比较新的是2013年的，亲测可用(MatLAB version of SP, a contrast algorithm for saliency detection, is relatively new in 2013, and pro-test is available.)

着重介绍了数字水印Patchwork 算法，并且利用Matlab编程实现了这一算法(Focuses on digital watermarking Patchwork algorithm, and this algorithm Matlab programming)

基于DCT的数字水印算法 通过Arnold变换对水印进行置乱，增加了水印的鲁棒性，成功的实现了水印的嵌入和提取。(Arnold transform digital watermarking algorithm based on DCT watermark scrambling to increase the robustness of the watermark, the watermark embedding and extraction. )

本算法先将彩色图像变换成灰度图像，在进行基于区域生长法进行图像分割(It segmented image with region growing. Then local adaptation luminance was computed via region-based bilateral filter. It outputted low dynamic range images in conjunction with tone mapping operator. )
