histogram matching for image enhancement

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

说明：  1、主要是产生0，1，2，3，阶贝赛尔函数图形。 2、产生线性调频信号和它的的频谱图。 3、产生单个脉冲的三维模糊图以及对应的等值图。 4、它是程序3的嵌套子程序，用于产生单个脉冲。 5、用于产生高斯和瑞利分布函数。 (These programs can produce 1、Bessel graph；2、LFM signal and its amplitude spectrum；3、ambiguous graph 4、Gaussian and Rayleigh function. )

一种用ICA实现特征提取的matlab程序，很有用的哦(ICA achieving Matlab feature extraction process, a very useful oh)

通过MATLAB对点云数据生成三维网格,并将三维网格做四边形网格细化处理。其中还有专门生成三维网格点云的MATLAB程序( This example shows how a triangular mesh can be resampled on a meshgrid -generated square grid. We illustrate the usage of both functions gridtrimesh and mxgridtrimesh . These two should produce identical results. Funcion mxgridtrimesh is a compiled MEX function written in C and should quicker than)
