tbd算法动态规划实现

说明：  matlab图像处理常用命令收集，很有用的，可以省很多时间(matlab image processing common command collection, very useful, can save a lot of time)

this is program to to add noise to an image,you have to first set path to "C:dspprojects"and copy any image(512*512) to that path...

信息隐写 构造完美矩阵编码嵌入 SPIE2011_stego_design_v0.9(Information steganography construct the perfect matrix coding embedded)

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.

基于matlab的算术编码设计，里面的程序均得到验证(Arithmetic coding matlab-based design, which the program have been validated)

三角分解法亦称因子分解法，由消元法演变而来的解线性方程组的一类方法。设方程组的矩阵形式为Ax=b，三角分解法就是将系数矩阵A分解为一个下三角矩阵L和一个上三角矩阵U之积：A=LU，然后依次解两个三角形方程组Ly=b和Ux=y，而得到原方程组的解，例如，杜利特尔分解法、乔莱斯基分解法等就是三角分解法(The triangular decomposition method, also called factor decomposition method, is a kind of method of solving the linear equation group by the evolution of the elimination method. A form of matrix equations Ax=b, triangular decomposition is the coefficient matrix A is decomposed into a lower triangular matrix and an upper triangular matrix L U product: A=LU, followed by the solution of two triangular equations Ly=b and Ux=y, and get the original equations, for example, Doolittle method, Jo Lessky decomposition is a triangular decomposition method)

说明：  Patton Coupla 工具包，包含常见的时变和非时变Copula代码(Patton Coupla Toolbox)

降噪处理的代码，内有说明。不同于传统小波降噪技术，使用非正交小波，使得图像中的相位信息得以保存。处理的效果也是比较好的。

matlab实现的图像标注开源代码，极有参考价值。(matlab implementation of image annotation open source code, and a valuable reference.)
