加州理工经典的摄像机标定程序，张正友博士的文章算法(The camera calibration program of the California Institute of Technology, the article algorithm of Dr. Zhang Zhengyou)

说明：  编程实现灰度图像的频域滤波算法。使用Matlab实现不延拓和延拓两个版本。对于延拓和不延拓版本，在理想低通滤波器、巴特沃斯低通滤波器和高斯低通滤波器上比较两者的区别；对于延拓版本，比较不同参数设置对上述三种滤波器滤波结果的影响。(Program to realize the filtering algorithm of gray image in frequency domain. Matlab is used to realize two versions of no extension and extension. For the extension version and the non extension version, the differences between the ideal low-pass filter, Butterworth low-pass filter and Gauss low-pass filter are compared; for the extension version, the effects of different parameter settings on the above three filter results are compared.)

说明：  使用PSTD计算方法实现的3维时间反转镜像技术算法，可用于声学及电磁学成像(A Time Reversal Mirror Algrithm devopled by the 3 dimensial PSTD numerical method, it can be used in acousic and electromagnitic imaging field)

利用视频三帧视频的差值，识别运动物体。视频操作为AVi格式(The moving object is recognized by the difference between the two frames of video)

说明：  LSCN彩色图像增强算法，PCNN算法的优化改进(algorithm of LSCN color image enhancement)

说明：  基于matlab的语音信号处理快速傅里叶变换程序(Fast Fourier Transform Program for Speech Signal Processing Based on MATLAB)

数学形态学应用二值图像边界细化，以及二值图像骨骼化( Application of mathematical morphology refined binary image border, as well as binary image skeletonization )

说明：  实现了一个二维小波分解、重构程序，对一副16*16的数字图像进行了二层小波分解和重构。(A two-dimensional wavelet decomposition and reconstruction program is implemented, and a 16*16 digital image is decomposed and reconstructed by two-level wavelet.)

shanChen两相流LBM的c版源代码，参考shanChen.m修改的，希望对不太熟悉Matlab的有所帮助(c code of liquid-liquid flow of shanchen)

问题：找出一个短字符串在一个长字符串中的精确匹配。 要求：基于BWT压缩和FM索引技术的序列匹配，用Burrows-Wheeler transform算法解决该问题。(Problem: find the exact match of a short string in a long string. Requirements: BWT-based compression and indexing techniques sequence matching FM, with the Burrows-Wheeler transform algorithm to solve the problem)
