改进了的动态视频目标跟踪程序，跟踪效果很好，大家放心下载！(Improved tracking of dynamic video program, track good effect, and we rest assured downloads!)

提取AVI格式视频文件为一帧一帧的jpg格式图片(Extraction of AVI format video files to a jpg format of a picture)

图像检索。通过计算所要检索的图像与图像库中的距离dis，dis最小者与检索图像同类。(image retrieval. Calculated to be indexed images and pictures of the dis the distance, the smallest dis with similar image retrieval.)

用块匹配法进行运动估计的matlab实现方法，返回运动矩阵(block matching method used for motion estimation method of Matlab, the return movement Matrix)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图( 1. Using Matlab generated sine wave, square wave, and the white noise signal, and displays the respective time-domain waveform 2. The FFT transform, showing each spectrum, where the sampling rate, frequency, data length choice 3. Rms signal to make the three maps, power spectra, as well as the number of rms spectra 4. With the inverse Fourier transform IFFT restore the signal and displays the recovered time-domain waveform sinusoidal signal)

说明：  人脸识别提出的LBP特征计算程序，简单实用的特征，可以得到统计的直方图特征(LBP features of face recognition proposed by the calculation procedure, simple and practical features of the histogram statistics can be characteristic of)

在图像中加入椒盐噪声的源代码，编译后的可执行文件须带参数运行(the image Salt and Pepper to the noise source, the compiled executable file parameters required to bring Operation)

图像分割关系到目标识别的精度，是目标检测的关键一步，其中提供了一些图像分割的代码，主要为otsu算法的分割方法，很实用(s related to the accuracy of target recognition, image segmentation is a critical step in target detection, provides some image segmentation code, very useful)

本例程序包含OMP、SP、IRLS、CoSaMP等重构算法，比较性能优劣。(The example application consists of OMP, SP, IRLS, CoSaMP reconstruction algorithm, and compare performance advantages and disadvantages. )

说明：  克里金算法2.0版本，对二维插值有详细的工具箱(kriging algorithm V2.0 for matlab )
