m序列产生子函数 gold序列产生子函数 自相关函数和互相关函数计算子函数 调用子函数[s,k,pn]=m(c,b0)产生第二条m序列(function [Rm]=Rm(golda,goldb) 自相关函数和互相关函数计算子函数 N=11 n=2^N-1 Rm(1)=sum(golda.*goldb)/n for k=1:n-1 Rm(k+1)=sum(golda.*circshift(goldb,[0,k]))/n end Rm )

数字水印中，对于水印的置乱方法：Arnold置乱，通过改变像素点的位置增强水印的鲁棒性(Digital watermark, the watermark scrambling for ways: Arnold scrambling, by changing the position of pixels increase the robustness of the watermark)

调频步进信号的产生matlab方式。希望有用！(generating step frequency signal use matlab!)

对位图图像利用JPEG标准进行正交变换、量化、扫描从而达到压缩，同时解压显示其压缩图像。(Bitmap image using JPEG standard orthogonal transformation, quantization, scanning to achieve the compression, and decompression display the compressed image.)

在这个分支中，主要是对标准粒子群算法的惯性因子、收敛因子（约束因子）、“认知”部分的c1，“社会”部分的c2进行变化与调节，希望获得好的效果。(In this branch, mainly to the standard particle swarm algorithm of inertial factor, convergence factor (constraints), "cognitive" part of c1, "social" part of the c2 changes and adjustment, hope to get good results.)

本程序主要通过EMD求IMF，边际谱图和瞬时能量图(This procedure mainly seek through EMD IMF, marginal spectrum and instantaneous energy diagram)

速度非常块，效果接近blsgsm。堪称去噪的又一突破。 OWT SURE-LET SOFTWARE FOR MATLAB ******************************** Florian Luisier, Thierry Blu and Michael Unser Biomedical Imaging group Swiss Federal Institute of Technology Lausanne (EPFL), Switzerland. March 2007 This software implements the algorithm described in: [1] F. Luisier, T. Blu, M. Unser, "A New SURE Approach to Image Denoising: Interscale Orthonormal Wavelet Thresholding," IEEE Transactions on Image Processing, vol. 16, no. 3, pp. 593-606, March 2007. (Very block, the effect close to blsgsm. Denoising can be another breakthrough.
