Joint entropy
说明: 计算两个离散变量x和y的联合熵z = H(x,y)。 输入:x,y:两个相同长度的整数向量输出:z:联合熵
可以使用,有利于学习目的(Compute joint entropy z=H(x,y) of two discrete variables x and y. Input: of x, y: two integer vector of the same length Output: z: joint entropy
good for learning purposes)

6image-recover
将一幅M×N的灰度图像用3×3平均滤波器进行模糊,分别再加上一定的高斯
噪声和均匀噪声。然后,设计一个维纳滤波器对这两幅图像进行复原,分别
计算这两幅图像复原前后的PSNR。(Gray-scale image of a MN 33 average filter is vague, respectively, plus a Gaussian noise and uniform noise. Then, design a Wiener filter to recover these two images, the two images before and after the recovery of PSNR were calculated.)

CSR_Denoising
该算法首先通过字典学习得到含噪图像的冗余字典,然后对相似的图像块进行聚类构成块群,并通过迭代收缩和L1正则化约束,对同类的图像块在字典上进行稀疏表示,以达到降噪的目的。实验结果表明,在常规的图像处理上,本文提出的算法能较好的保留图像的结构信息,与K-SVD和BM3D等现有的流行算法相比,具有更高的峰值信噪比(PSNR)(It firstly get the redundant dictionary of a noised image by dictionary learning.Then,the image patches are gathered according to their similarities.Meanwhile,the similar patches get sparse representation showed in dictionaries by iterative shrinkage and L1 regularization constraints and eventually the image is restored and noise is removed.The experimental results indicate that the proposed algorithm can well preserve the structure information of the common image with a higher Peak Signal to Noise Ratio(PNSR),compared with state-of-the-art algorithms,such as K-SVD and BM3D)
