highboost filter for image enhancement

说明：  很详尽的傅里叶变换课件，可以学习下，适合初学者。(Fourier transform is very detailed courseware, you can study, one for beginners.)

用周期图法求解功率谱曲线，并搜索信号频率值(Periodogram method for solving the power spectrum curve, and search for the signal frequency value)

下载的，求方程组的程序，可以借鉴下，挺好的(Downloaded, find the program equations, can learn, the very good)

二维空间中的多边形逼近。确定三个顶点a，b，c并且其函数值按从小到大排列。将二维空间中的多边形三个顶点的函数值按从小到大顺序排列， 判断三点或三点函数值的距离是否小于给定阈值.若小于阈值停止循环，得最优解x0=a(Two-dimensional space polygon approximation. Determine the three vertices a, b, c and its function value in ascending order. The three-dimensional space polygon vertices function values ​ ​ in ascending order, function to determine the three o' clock or three values ​ ​ of the distance is less than a given threshold and if less than the threshold value to stop loop, get the best solution x0 = a)

【matlab编程代做】振动响应谱 可以作为参考使用学习([Do] matlab programming generation vibration response spectrum can be used as a reference study)

声纳技术实验常用水声信号及其处理方法，包括CW信号产生，LMF信号产生(Sonar technology experiments commonly used in underwater acoustic signal processing methods, including the CW signal generator, Model LMF signal generator)

The codes are the matlab platform. they are begin simple to complex.

该源码是基于划分的模糊聚类算法，matlab带有自己的fcm算法，此次上传的算法是自己编写的(The source is divided based on fuzzy clustering algorithm, matlab with its own fcm algorithm, the upload algorithm is written in their own)

包含多种定位算法，如质心定位、DV-hop、APIT、三角形定位，网格定位等。(Includes various localization algorithms,for instance,centriod,APIT,DV-HOP,Grid Scan.)
