将原图像进行退化处理（选择大气湍流导致图像模糊时相应的PSF），然后将退化后的图像进行复原（使用维纳滤波、直接逆滤波）.(The original image degradation process,and then restore the degraded image with Wiener filtering and inverse filtering.)

基于仿射变换的图像匹配程序，这是基于mablab的一个主程序(Affine transformation based on the image matching process, which is based on a main mablab)

利用idl语言实现图像的数学形态学开闭重建运算，比提取梯度图像。(Idl language use mathematical morphological opening and closing image reconstruction operations, compared to extract gradient image.)

此程序计算图像的七个不变矩，提取出图像的形状特征，可用于图像检索。(This procedure of calculating the image of seven invariant moments, the shape of extracted image features, can be used for image retrieval.)

可以获取连通域的最小外接矩形，然后做些其他处理(You can get the minimum external rectangle of a connected domain,and you can do something else.)

使用contourlet变换对图像进行去噪处理(Image denoising using contourlet transform)

fingerprint normalise

基于特征匹配的英文印刷字符识别，里面有实验所需的图片和具体的代码(English printed character recognition based on feature matching, which contains the pictures and specific code needed for the experiment)

针对现有方法存在的隐藏容量低、操作不灵活的缺陷，文章提出了一种基于无损压缩的加密图像可逆 信息隐藏算法。(In view of the defects of low hiding capacity and inflexible operation of the existing methods, this paper proposes a reversible information hiding algorithm for encrypted images based on lossless compression.)

本代码可以实现统计彩色图像RGB三个通道内的交流分量，通过对比确定，图像是否经过高斯模糊篡改。(This code can realize statistical color image RGB three channels in the ac component, by comparing the sure, whether image through gaussian blur manipulation.)
