K2算法

esprit算法，辛苦搜集的，很有用，希望能帮助更多的人，仅供参考(esprit esprit esprit esprit)

这是一基于MATLAB的复调制ZOOM-FFT的研究和实现的一篇文章，为的是提高频率分辨率。(This is a MATLAB-based complex modulation ZOOM- FFT Research and Implementation of an article, To improve the frequency resolution.)

这是利用一个simulink环境下简单得PPT文件，希望对大家有帮助，谢谢！(This is the use of a simple simulink environment have PPT file, we want to help, thank you!)

集合卡尔曼滤波的Matlab程序，enkf-matlab-0.30，最新版本(EnKF-Matlab is designed primarily as a research and study tool. As a consequence, speed and memory usage are given a lower priority than simplicity and ease of use)

M=512 原图像长度 N=64 K=8 I=zeros(M,M) J=zeros(N,N) BLOCK=zeros(K,K) 显示原图像 I=imread( f:ceshiyuanshitu.bmp ) figure imshow(I) xlabel( 原始图像 ) 显示水印图像 J=imread( f:ceshilogistic_nuaa64.bmp ) figure imshow(J) xlabel( 水印图像 ) 嵌入水印 tem=1 for p=1:N for q=1:N x=(p-1)*K+1 y=(q-1)*K+1 BLOCK=I(x:x+K-1,y:y+K-1) BLOCK=dct2(BLOCK) if J(p,q)==0 a=-1 else a=1 end BLOCK(2,1)=BLOCK(2,1)*(1+a*0.01) BLOCK=idct2(BLOCK) I(x:x+K-1,y:y+K-1)=BLOCK end end 显示嵌入水印后的图像 figure imshow(I) xlabel( 嵌入水印后的图像 ) imwrite(I, f:ceshiembedded.bmp )

it includes implementations of different DIP algorithms all are tested and working fine
