Chirp-Scaling-Algorithm-with-RCM

在DCT域，利用8*8分块DM方法，嵌入隐藏信息。可设置量化步长、选择各种经典的攻击方式和控制攻击强弱。返回误码率和峰值信噪比。利用Matlab编写。(In the DCT domain, the use of 8* 8 block DM methods, embedding hidden information. Quantization step size can be set to choose a variety of classic attacks and control the strength of the attack. Return to the bit error rate and peak signal to noise ratio. Prepared using Matlab.)

精心编写的信号处理的实验指导书，程序在matlab上运行。(Signal processing and well-written experimental instructions, the program running in matlab.)

Matlab的帮助文章，中文版，很有用，使用方便(Matlab help articles, the Chinese version, very useful, easy to use)

一个用simulink做的模糊PID自适应系统，通过三个模糊FIS：dkp,dki,dkd来分别控制Kp,Ki,Kd，以达到PID参数可自动调整的目的。(A simulink do with self-adaptive fuzzy PID system, through three fuzzy FIS: dkp, dki, dkd to control the Kp, Ki, Kd, in order to achieve automatic adjustment of PID parameters can be objective.)

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 )
