MATLAB-dct-and-idct

Matlab程序，用于图像去噪声处理，特色是能够在去噪时保护图像边缘，是非线性滤波处理(Matlab program for the image to deal with noise, features that can protect the edge denoising is nonlinear filtering deal)

matlab检测直线交点源程序在matlab6,5下已调试通过 不错的(Matlab detection line intersect point source in matlab6, have been debug through good under 5)

四元数类 matlab程序 包含四元数相关运算(quaternion class)

基于拓展RPC模型的多源卫星遥感影像几何处理 转化程序(RPC model-based development of multi-source remote sensing image processing conversion process geometry)

去隔行的算法，具有可视化。大家可以作为参考，也想学习别人的代码(deinterlace)

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 S = 0 H = 0 return } if (delta == 0){ H = 0 return } else if(R == max){ if (G >= B) H = (G- B)/delta // between yellow & magenta else H = (G- B)/delta+ 6 } else if( G == max ) H = 2+ ( B- R )/delta // between cyan & yellow else if (B == ma)

基于互信息的刚性配准，利用了Powell算法和黄金分割算法，效果还不错(Based on Mutual Information rigid registration, Powell algorithm and the use of the golden section algorithm, the results were good)

说明：  matlab图像配准算法，确定归一化互相关最大值及其位置，利用相关找到的偏移量，判断两幅图是否相同。(MATLAB image registration algorithm determines the maximum normalized cross-correlation and its location, and uses the offset found by correlation to determine whether the two images are the same.)

基于颜色的图像检索，采用累积多种距离衡量算法(Color-based image retrieval, using a variety of distance measuring algorithm cumulative)

说明：  模拟脉冲串回波信号（脉冲周期1ms），快时间匹配滤波，慢时间MTD，提取目标的距离-速度信息；(The echo signal of analog pulse train (pulse period 1ms), fast time matched filtering, slow time MTD, extracting the range velocity information of the target;)
