：数字水印技术作为数字媒体版权保护的有效办法，近年来在国内外引起了人们极大的兴趣。作者采用了DCT离散余弦变换的算法，对图像这种多媒体数字作品进行了数字水印的嵌入和检测研究。并且使用了高效实用的编程工具MATLAB来介绍了一种DCT域的图像数字水印嵌入和提取的(BASIC_WM.M ..........................................cellauto.m ..........................................dctwatermark.m ..........................................detectbasic_wm.m ..........................................plotcorr_coef.m ..........................................wavedetect.m ..........................................wavedetect2.m ..........................................wavemarksvd.m ..........................................wavemarksvd)

这是一个关于图像处理的程序，能够将像素比较低的图像变成分辨率高的图像.(This is a matter of image processing procedures, can be relatively low-pixel high resolution image into the image.)

匹配算法，可以完美运行，对于初学者有着很好的参考价值(Matching algorithm, can be a perfect run, has a very good reference for beginners)

用于虹膜定位……定位外圆之前需要进行边界跟踪，此程序实现此功能(For Iris Location ... Location ... before the need for outer border tracking, this procedure realize this feature)

区域生长 冈萨雷斯 matlab 集合了区域生长函数和使用过程文件(The region growing Gonzalez matlab collection of regional growth function and process of using file)

说明：  基于距离变换的分水岭分割算法，该算法可以实现对粘连物体的分割。(Watershed algorithm)

用matlab实现图像变形的实验实例，采用idw 和 rbf 算法(imagewarping using idw&rbf algorithms in matlab)

说明：  图像的Laplace金字塔分解与重构算法。(Laplacian pyramid decomposition and reconstruction of image. )

基于matlab指纹图像的分组法方向场求法(Based on matlab the fingerprint image dividing group method direction field is also given )

说明：  SSR、MSRCR、Retinex和暗通道四种去雾算法的matlab实现，亲测好用，改图片名可以直接运行，效果很好(The matlab implementation of SSR, msrcr, Retinex and dark channel defogging algorithms is easy to test and use. Changing the image name can run directly, and the effect is very good)
