Wavelet_IRLS
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)

特征选择之relief-F的MATLAB实现
Relief-F 算法是由 Kononenko 在 Relief 算法基础上扩展得到的,可以用来解决多分类与回归问题。 Relief-F 特征选择算法利用特征与类别间的相关程度判别特征的敏感程度,敏感的特征能使同类样本靠近,非同类样本远离。基本思想是: 先随机从总样本集 D中获取一个样本 R, 然后在 与 R 同类样本集中和与R 异类 样 本 集 中 各 获 取 k 个近 邻 样 本, 在 特 征 集 F中如果某个特征上异类样本的距离大于同类样本,则这个特征是有利于分类的,增加其权重,重复 n 次 取所有结果的均值作为每个特征的最终权重值.

rgb to HSV,很有用,调试成功,可以应用(rgb to HSV,#include "stdafx.h"
#include <iostream.h>
void main(float R, float G, float B, float& H, float& S, float&V)
{
// r,g,b values are from 0 to 1
// h = [0,360], s = [0,1], v = [0,1]
// if s == 0, then h =-1 (undefined)
float min, max, delta,tmp
tmp = R>G?G:R
min = tmp>B?B:tmp
tmp = R>G?R:G
max = tmp>B?tmp:B
V = max // v
delta = max- min
if( max != 0 )
S = delta/max // s
else
{
// r = g = b = 0 // s = 0, v is undefined

jpg_encoder_and_decoder_matlab
自己用matlab写的灰度图像压缩解压程序
jpegencoder可以打开图像压缩后存储为c.jpg(只限于灰度图像)
jpegdecoder只适用于把jpegencoder的c.jpg解压,还不可以对任意图像解压,有待以后完善
