dct隐写技术matlab实现资料。算法原理：通过在一个图像块中调整两个DCT系数的相对大小，隐藏秘密信息。 将载体图像分为8×8的块，做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if（要隐藏信息‘1’） make else make 逆DCT变换，还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

电子文档介绍利用matlab进行计算机仿真教程。(Electronic document describes the use of computer simulation matlab tutorials.)

使用Matlab编程实现发送端信源编码（图像压缩）和接收端信源解码（图像重建），其中的编解码算法可采用基于DCT变换的JPEG图像压缩标准；测试图像加噪，然后对去噪后的图像进行压缩与重建，分析压缩性能；研究基于下采样和内插的图像压缩算法；可将8bit/pixel灰度图像扩展至24bit/pixel彩色图像，或者采用无损压缩算法对图像压缩。(Sender using the Matlab programming source coding (image compression) and the receiver source decoding (image reconstruction), one of the decoding algorithm can be used DCT-based JPEG image compression standard test image with noise, then the denoised image compression and reconstruction, compression performance analysis of down-sampling and interpolation based on image compression algorithm 8bit/pixel grayscale images can be extended to 24bit/pixel color images, or the use of lossless compression algorithms for image compression. )

此文档是介绍孤子在饱和介质中传输的matlab仿真过程，孤子仿真网上有很多文章，可是均不带源码，恰巧本人编了些就都传上了，希望对各位有用。(Introduction This document is at saturation soliton transmission medium matlab simulation process, there is a lot of soliton simulation online article, but not with source code, I made something happen on both a mass on the hope that useful to you.)

一、 利用MATLAB产生下列连续信号并作图 （1） x(t)=-2u(t-1),-1<t<5 x(t)=cos(100t)+cos(3000t),设-0.1<t<0.1(one, Using MATLAB produce the following continuous signals and mapping (1) x (t) =- u (t-1)-1)

改进版本的泰森多边形法LEACH聚簇算法，比普通LEACH更为高效(leach voronoi)

这是本人下载和编译过的关于大津法二值化的matlab代码，效果比较好，可以作为分割的有效辅助(This is, I downloaded and compiled on the Otsu binarization method of matlab code, the effect is better, can be used as an effective auxiliary partition)

整数小波变换与图像压缩 用MatLAB实现图像的整数小波变换，对行和列各做一次。采用最简单的S小波，它是Haar变换的整数形式。(integral wavelet transform and image compression .To realize the integral wavelet transform based on the Matlab in rows and columns. Using the simple S wavelet ,which is integral form of the Haar transform)
