u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A1) r1 = [] for i=1:r for j=1:c if A1(i,j) > B1(i,j) r1(i,j)=A1(i,j) else r1(i,j)=B1(i,j) end end end r1= double(r1(:,:,1)) C=blkproc(r1,[8 8], idct2 ) round(C) C1=idct2(r1) figure imshow(uint8(C)) figure imshow(uint8(C1)) imwrite(uint8(C), dct8x8min.jpg )

sift匹配程序在matlab环境下的实现，包括特征提取与匹配(the sift match program realization in Matlab environment, including feature extraction and matching)

this is matlab version of removal of noise

EMD 方法在理论上可以应用于任何类型的信号的分解， 因而在处理非平稳及非线性数据上，具有非常明显的优势,适合于分析非线性、非平稳信号序列，具有很高的信噪比。(EMD decomposition method in theory can be applied to any type of signal, which in the non-stationary and nonlinear data, with a very distinct advantage, suitable for analyzing nonlinear and non-stationary signal sequence, with a high signal to noise ratio .)

产生一个随机输出信号在瑞利信道上可以用来生成MATLAB仿真模块。(This program will generate a random signal output by Rayleigh channel can be used to generate MATLAB simulation module.)

很好很强大,是关于双极性基带数据信号对载波进行角度调制产生BPSK信号的，有用的就下取用(strong，just for student who need it.)

本文件将普通RGB图像转化成二值图像，方便后续处理(This document will be an ordinary RGB image into binary image, to facilitate follow-up treatment)
