盲水印嵌入提取-已实现

这是一个基于超像素算法的分割小软件，可以用于图像的分割，但是没有语义。使用者如果用于商用，要联系软件中的作者(This is a small software based on super-pixel algorithm, which can be used for image segmentation, but without semantics. Users for commercial use should contact the authors in the software.)

说明：  简单的graph cut 算法，初学者适合(Simple graph cut algorithm for beginners)

简单明了地计算两幅图片的相关性，绝对好用，亲身示范(Correlation coffiention)

数字水印算法实现（matlab程序包），包含有DCT水印嵌入算法，DWT水印嵌入算法，以及水印攻击和性能测试程序。参考价值极大(digital watermarking algorithm (Matlab package), including a watermark embedded DCT algorithm, DWT algorithm embedded watermark, watermark and attack and performance testing procedures. Great value)

英文文本的相似度计算，分别从词形、词序、词义等方面进行权重计算，得到相似度结果(English text similarity calculation were re-calculated from the word form, word order, meaning, etc. right, the similarity results)

基于Hessian矩阵增强提取二维或三维医学图像中的血管(Vessel enhancement and extraction from 2D or 3D medical images)

说明：  基于小波变换的图像融合用matlab实现的源代码(image fusion)

利用八方向的sobel边缘检测，实现对图像多梯度的梯度检测，检测出的边缘信息更加平滑连续。(Eight direction Sobel edge detection is used to realize gradient detection of image multi gradient, and the edge information detected is more smooth and continuous.)

射线追踪算法的基础理论和学习，入门课件，适用于地震学(The basic theory and learning of ray tracing)

We extend the well-known Shi-Tomasi-Kanade tracker by introducing an automatic scheme for rejecting spurious features. We employ a simple and efficient outlier rejection rule, called X84. Experiments with real and synthetic images confirm that our algorithm makes good features to track better
