非平稳时变分析工具箱。现代信号处理的重要工具。(Non-stationary time-dependent analysis toolbox. An important tool in modern signal processing.)

The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.

说明：  本书详细讲述了MATLAB的基础用法、编程技巧及应用实例，是学习MATLAB的优秀参考书。(The book describes in detail the basis for the use of MATLAB, programming techniques and application examples, is an excellent reference book to learn MATLAB.)

关于质心定位的matalab原代码，做定位方面毕设的人可以用！(Matalab centroid location on the original code, so positioning complete set of people can use!)

在MATLAB实现的用C实现的KNN算法，输入训练数据文件，和test文件，进行预测分类，并且可以与真实情况比较测试预测正确百分比(Implemented in MATLAB KNN algorithm implemented in C, the input training data file, and test files, to predict the classification and testing with the real situation is more correct percentage of predicted)
