改进的均值偏移跟踪算法，带有示例视频，可完成对选定目标的实时跟踪(Improved mean shift tracking algorithm, with a sample video, to be completed by the real-time tracking of selected targets)

快速计算一维信号的塔式谱峭度图，选择谱峭度最大值区间，方便确定所需滤波器中心频率及带宽。(Computes the fast kurtogram of signal x.This fast algorithm uses a pyramidal decomposition of the signal into a user-specified number of levels (a good choice is nlevel = 8). The first level is the classical kurtosis of the signal, the second level is the spectral kurtosis in 2 octaves, the third level the spectral kurtosis in 4 half-octaves, etc. Non-integer levels refer to divisions into third octaves. Here below is an illustration on how the frequency band is successively split when increasing the level)

MATLAB 很重要的文件 很重要的文件很重要的文件很重要的文件很重要的文件( this is a importent this is a importent this is a importent this is a importent this is a importent )

各种分类器的源码，有注释和功能描述,马氏，贝叶斯，最大似然等(Various classifier source, there are notes and functional description)

离散点的极值寻找。一组离散数据中的极大值或者极小值点，不同于fmax函数(Discrete extremum looking. Maxima or minima of a set of discrete data points, unlike fmax function)

本附件包含在matlab环境下双谱分析源码的m文件，除了高阶谱，是用的比较广泛的一种。主要用于TDOA及弱信号检测等。可以动手下载后在matlab下运行之。和我前次发的高阶谱分析帖子一样，是要手动加入matlab高阶谱工具箱！ (This annex is included in the matlab environment bispectral analysis of source code of m documents, in addition to high-end spectrum, is widely used as a comparison. Mainly for TDOA and weak signal detection. Can begin download matlab running it. And my previous post issued order spectral analysis, is to manually add order spectrum matlab toolbox!)
