非平稳信号的瞬时频率、群延时、信号生成方法(Sub-stationary signal the instantaneous frequency, group delay, Signal Generation)

image segmentation, normalized cut for clustring

说明：  这是独立分析针对图像分离的代码，很清楚的。(This is a separate code for the image of the independent analysis, it is clear.)

用LCS方法解决字符匹配问题，用到动态规划的思想。原创(LCS solution with matching characters, the idea of using dynamic programming)

用元胞自动机模拟交通流,这是一个在二维格子上的元胞自动机，可以当做游戏来看看(use cellular_automata to simulate the traffic flow)

说明：  通过matlab环境，将rgb24格式的avi文件提取出bmp格式文件并逐帧保存。(transfer RGB24 avi files to bmp images.)

心电信号奇异值分解，用于从腹壁信号中分离出母体心电参考信号(ECG singular value decomposition)

老外写的小波变换的工具箱，基于MATLAB环境；压缩包内有详细的说明和相关Demo，参考价值较高。(Written by foreigners Wavelet Toolbox, MATLAB-based environment compressed packet has detailed instructions and Demo, a high reference value.)
