将Radarsat2极化SAR图像数据转换为散射矩阵及相干矩阵T3的matlab代码,附上的图像文件是用Enviview软件截取转存的各通道实部虚部文件,以及lutsigma.xml查找表文件.作者辛苦所做,希望对SAR初学者有所帮助.-Will Radarsat2 polarization SAR image data is converted to T3 scattering matrix and the coherent matrix of matlab code, the attache

对24位的彩色图像用中位切分(中位区分）法将其转换成8位索引图像，并且生成对应的颜色查找表。-median-cut algorithm,8-bit index map, lookup table,256 colors,

本代码实现了基于卡方分布(nakagami 分布)的恒虚警检测(CFAR)，通过在查找表的形式，实现参数估计和阈值估计，完成对目标的检测。-The code based on the chi-square distribution (nakagami distribution) of the CFAR (CFAR), through the form of a lookup table to achieve the threshold parameter estimates and estima

For a 24-bit color image (Lena.bmp), statistics all used colors in this image, design the median-cut algorithm to generate a lookup table. And convert the 24-color image to 8-bit index image, compare the difference between them.

Matlab 图像处理approxfcn.m源程序 用于图像处理的approxfcn逼近函数 - G = APPROXFCN(F, RANGE) returns a function handle, G, that approximates the function handle F by using a lookup table.RANGE is an M-by-2 matrix specifying the input range for each of the M inputs t
