基于DCT数字图像复制粘贴篡改被动取证

对候选人得票进行统计，设有3个候选人，最终只能有1人当选为领导。(Statistics on the number of votes a candidate with three candidates, we can only have one person elected as leader.)

实现了彩色图像上的DCT变换和DCT反变换(Color image on the realization of the DCT transform and inverse transform DCT)

水声合成孔径的波束形成，并采用fftsa和Etam算法分别进行仿真。集中在一个界面里。(Synthetic aperture acoustic beam forming and using fftsa and Etam algorithms are simulated. Concentrated in an interface where.)

函数edge的用法，几个算子的效果比较。(The use of edge functions, comparison of the effects of several operators.)

说明：  麻省理工学院小波理论教学课件，pdf版本打开，全中文，希望各位喜欢 (MIT wavelet)

说明：  图像置乱中的仿射变换，优点是加密和解密的不需要周期迭代，图像置乱效果好(it is good for image scrambling becaus of low compute complexity)

这是一本经典的移动通信方面的教程。涉及到ASK，PSK,FSK等调制方式，对想从事于通信方面的学生以及专业人士都很有帮助。(This is a classic tutorial for mobile communications. Related to ASK, PSK, FSK modulation, etc., on to the students engaged in the communications and professionals are very helpful.)

Solving ODEs with Matlab:Instructor’s Manual

能够将电厂DCS中提取的execl文件批量转换为mat文件并将各个变量以时间序列和测量数值的形式单独保存

对块匹配中的全局搜索进行改进，只用搜索整幅图像的一半像素，与全局搜索（FS）相比，精度没有降低而时间减少了一半。(improved from full search, the matching time-consuming is nearly half of FS, but the matching accuracy is not reduced.)
