稀疏表示的毕业参考论文，在图像去噪、图像修复、人脸识别及压缩感知等图像处理领域中的应用进行了总结.(Sparse representation of graduation reference papers, summarized in the image denoising, image restoration, face recognition and compressed sensing and other image processing applications)

matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如未修改，可提取隐藏信息。当有修改发生时，可以定位修改的位置，并在图上标出。标识面积占修改面积的75％，一般修改都能标出(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications)

图像匹配，通过选定模板图像和要要匹配的图像，在要匹配的图像中用红色方框标记处匹配的区域。(Image matching, through the selected template image and want to match the image, to match the image using the red mark at the box matches the area.)

用MATLAB实现亚像素角点检测，简单实用(Using MATLAB to achieve sub-pixel corner detection, simple and practical)

自己编写的字幕提取代码，matlab简单易用(Caption extraction)

小波算法，在计算式，通过图像对其进行分析估计，可以直观的看到它对函数的时域和频域的改变(Wavelet algorithm, calculation, estimated by image analysis of them, you can visually see that it functions in time domain and frequency domain changes using the compression miu worth PSO )

本压缩包包含了图像处理中稀疏表示的相关文献以及相关代码(This archive contains a sparse representation of image processing literature and related code)

伪彩色增强的matlab程序，主要基于空间域灰度级－彩色变换,算法清晰,效果较好. (pseudo-color enhanced Matlab procedures, mainly on the spatial domain gray level-color transformation, the algorithm clear. effective.)
