说明：  脆弱性数字水印能为多媒体内容完整性认证和篡改检测提供有效的解决方案。该文对用于图像认证的脆弱性数字水印技术的研究 现状、一般原理、基本特征、典型算法进行了综述(The vulnerability of digital watermark for the integrity of multimedia content authentication and tamper detection to provide an effective solution. The image authentication for the vulnerability of digital watermarking technology, research, general principles, basic features, typical algorithms are reviewed)

易语言图像混色汇编版源码，易语言写的图形图象编程，很好的参考。(Easy language image color mixing assembly version of source code, easy to graphics programming language to write, a good reference.)

实现一个信号的WVD变换，针对的信号是非平稳的随机信号(To achieve a WVD transformation of a signal, the signal is a non-stationary random signal.)

说明：  基于单幅图的非均匀校正算法，包括OMP和GPSR的重构算法(Nonuniformity correction algorithm based on single image)

在空间域上进行特征提取，用于局部或全局的特征检测，结合广义高斯分布，实现图像的质量评价(Feature extraction is carried out on the spatial domain, which is used for local or global feature detection, and the image quality evaluation is realized by combining the generalized gaussian distribution.)

可以用来计算MTF值，用matlab编写的，数据文件需要为Excel格式。(MTF can be used to calculate the value, using matlab prepared.)

本代码主要给出了激光粒度仪颗粒散射光强分布以及4种粒度反演算法，以及4种算法之间的比较。四种反演算法为：TSVD、Chaine、Tikhonov和l1正则化。(The code gives the Zetasizer particle scattering intensity distribution, and four kinds of particle inversion algorithm, as well as a comparison between the four algorithms. Four kinds of inversion algorithm is: TSVD, Chaine, Tikhonov and l1 regularization.)

说明：  采用surf算法对两幅较低重叠度的图像进行拼接(Image mosaic using surf algorithm)

sift和surf特征点提取，然后进行配准，通过ransac进行提纯(Sift and surf feature points are extracted, then registered and purified by RANSAC)
