非锐化掩膜,用于DR图像的对比度增强算法，这只是一个简单的算法过程，(unsharp masks)

压缩感知CS——采用小波变换进行稀疏表示，高斯随机矩阵为观测矩阵，重构算法为OMP算法，对256*256的lena图处理，比较原图和OMP算法在不同采样比例(0.74、0.5、0.3)下的重构效果，并各运行50次，比较算法性能PSNR和每次的运行时间 (Compressed sensing CS- using wavelet transform as sparse representation, Gaussian random matrix as the observation matrix and OMP algorithm as the reconstruction algorithm. Compare lena figure and the reconstruction results using OMP algorithm at different sampling ratio (0.74,0.50.3),then each runs 50 times, compare the performance of PSNR and each running time)

图像修复，使用曲率方法，热传递。边缘修复非常好，参考某博士论文写。(Image restoration, using the curvature method, heat transfer. Edge of the repair is very good, the reference of a doctoral dissertation.)

基于稀疏分解的欠定盲源分离，要求信号具有一定的稀疏性。(Based on sparse decomposition due to blind source separation, the signal has a certain sparseness.)

说明：  本程序使用MATLAB编程用于计算图片的视觉混乱度(Calculate the visual clutter of pictures)

程序先用fspecial函数产生运动模糊图像，再用维纳滤波进行恢复(Procedures first fspecial functions to generate motion-blurred image, and then carry out the restoration of Wiener filtering)

说明：  数字图像处理(Digital Image Processing)是通过计算机对图像进行去除噪声、增强、复原、分割、提取特征等处理的方法和技术。 [1] 数字图像处理的产生和迅速发展主要受三个因素的影响：一是计算机的发展；二是数学的发展（特别是离散数学理论的创立和完善）;三是广泛的农牧业、林业、环境、军事、工业和医学等方面的应用需求的增长(Digital Image Processing (DIP) is a method and technology of removing noise, enhancing, restoring, segmenting and extracting features from images by computer. [1] The emergence and rapid development of digital image processing are mainly influenced by three factors: first, the development of computer; second, the development of mathematics (especially the establishment and improvement of discrete mathematics theory); third, the growth of the demand for extensive applications in agriculture, animal husbandry, forestry, environment, military, industry and medicine.)

Porcupine deals with digital image watermarking. You can embed any visible watermark like a text or another image in any position, or store information invisibly inside using a secret key (password).

一种带有自适应阈值和动态支持区域的CSS角点检测算法，其效果被认为优于目前所有的CSS角点检测算法和大多数的其他类型角点检测算法。(a curvature scale space corner detector with adaptive threshold and dynamic region of support, it is considered to be the one of the best corner detection algorithms.)

本程序实现了提取图像中直线的功能。能够很好地提取出位于边缘上的直线段，其结果表示为两端端点坐标以及线段宽度(This program realizes the function of extracting the edge line in the image.The straight line segment at the edge can be extracted well, and the result is expressed as the end point coordinates and line segment width at both ends.)
