fft

说明：  利用非局部均值的算法对图像做去噪，速度比较快，但效果一般，存在一定局限性(Using non-local mean algorithm to denoise image is faster, but the effect is general and there are some limitations.)

圆阵常规波束形成与MVDR用于方位估计的比较，可以更改信噪比仿真两者的区别联系(uniform circle array based for estimating direct of arrival,CBF and MVDR compared with adjustable SNR)

基于多相结构的信道化接收机，sar图像去噪的几种新的方法，小波包分析提取振动信号中的特征频率。( Channelized receiver based on multi-phase structure, Several new methods sar image denoising, Wavelet packet analysis to extract vibration signal characteristic frequency.)

基于局部能量与模糊逻辑的红外偏振图像融合，该文与小波包，支持向量机等融合算法进行对比分析，说明该文算法的优势。(Infrared polarization image fusion based on local energy and fuzzy logic, this paper, wavelet packet, support vector machines and other fusion algorithm comparison analysis to illustrate the advantages of the proposed algorithm.)

一款新的数据分析工具，非常简单易用，用在系统辩识中(A new data analysis tools, very easy to use, used in System Identification)

给定原图像和降噪或者加了噪声之后的图像，计算峰值信噪比PSNR(calculate PSNR)

说明：  canny算子边缘提取。用matlab编写，并有详细的解释。(use matlab to canny edge detection operator,with a detailed explanation.)

能计算图像的灰度直方图，及其对应的灰度均值(calculate means ，variance，bins)

基于matlab的高帽变换，能很好地对图像进行一定的处理，实现图像的增强，线性特征的提取，为后续的处理做准备(Matlab-based top-hat transform good image processing, image enhancement, linear feature extraction, to prepare for subsequent processing)

说明：  物体运动的跟踪，比如行人和车辆等物体的跟踪(Tracking the motion of an object, such as a pedestrian or vehicle)
