filter

数字图像处理方面的常用操作 人脸识别 图像打开和保存 类似photoshop操作 (Digital image processing operations commonly used face recognition and preservation of the image to open a similar operation photoshop)

极化合成孔径雷达中，常用的精致极化lee滤波器程序，可以较好的表现出图像信息(Polarization synthetic aperture radar (SAR), commonly used delicate polarization lee program, we can better filter show image information )

含实验报告以及测试数据 基于离散点的构TIN算法 一、算法思想 （1）首先，找出离散点集中相距最近的两点，连接这两点形成TI、的初始基线。  （2） 然后，找出包含此基线的另外一个点构成三角形。寻找第三点的方法: △按Delaunav三角形的判断法则乎找第三点。 △或者.按距离基线中点最近的原则挤找第三点。 （3）连接孰点与基线的两个端点形成两条新边，构成三角形。  （4）抓这两条新边为基线，重复上述过程。直到两条新边扩展完成。  （5）重复上述过程，依次循环处理所有新边。直到所有离散点均成为TIN的端点。

matlab可以用来做小波变换的图像处理代码，可以用来做图像分割，融合。(matlab wavelet transform can be used to make the image processing code, can be used to make image segmentation, integration.)

压缩感知CS——采用小波变换进行稀疏表示，高斯随机矩阵为观测矩阵，重构算法为ILRS算法，对256*256的lena图处理，比较原图和IRLS算法在不同采样比例(0.74、0.5、0.3)下的重构效果，并各运行50次，比较算法性能PSNR和每次的运行时间(Compressed sensing CS- using wavelet transform as sparse representation, Gaussian random matrix as the observation matrix and IRLS algorithm as the reconstruction algorithm. Compare lena figure and the reconstruction results using IRLS algorithm at different sampling ratio (0.74,0.50.3),then each runs 50 times, compare the performance of PSNR and each running time)
