this code is thresholding image with fuzzy c-meam thresholding, it good result than Otsu method.

用DFT对离散信号进行谱分析,通过选用不同的加窗函数来抑制信号截断造成的频谱泄漏(DFT of a discrete signal spectrum analysis, by choosing different windowing functions to suppress the spectral leakage caused by the signal cut)

视频抓帧，抓到连续图像每一帧。适合做视频的朋友(Video frame, catch caught continuous image each frame)

平面波与涡旋波的干涉产干涉条纹，条纹出现位错。(Plane wave and vortex waves produce interference fringes, stripes appear dislocation.)

数字信号处理 系统文件的编写 库文件可以直接使用。(Digital signal processing system files and the writing of the library files can use directly. )

说明：  采用正交投影生成子空间算法来进行最大似然估计，程序已经运行出结果。可以放心使用(Orthogonal subspace projection algorithm for generating maximum likelihood estimates, the program has run out of results. Safe to use)

autocorrelation and crosscorrelation ..... basic idea about those stuffs.........

说明：  可以手动的选择区域提取图像中目标的质心。(extract the target image center of mass)
