interface for 3D image approximation

说明：  对一幅图像的进行小波包分解，然后提取每一层的系数(image of a pair of wavelet packet decomposition, and then extract the coefficient of each layer)

说明：  CRC校验的Matlab仿真，也可以认为是二进制除法。(CRC checksum of the Matlab simulation, it can be regarded as a binary division.)

说明：  关于matlab的一些语句讲解说明，包括最常用到得(On a number of statements on matlab, including the most commonly used were)

用于文本分析和分类的pLSA(Probability Latent Semantic Analysis)的Matlab算法，含有测试数据及算法原理介绍。也可用于图像分析。相比原来的版本，增加了示例程序demo.m，以实现可视化效果，用户更容易使用和理解pLSA算法。(For text analysis and classification of pLSA (Probability Latent Semantic Analysis) of the Matlab algorithm with test data and algorithm theory description. Can also be used for image analysis. Compared to the original version, an increase of sample programs demo.m, to achieve the visual effect, the user can more easily use and understand the algorithm.)

matlab用来计算mie散射的相函数以及单次散射反照率等(calculation for MIE)

离散小波变换，包括各层分解，消除了边界效应等问题(DWT，including every layer)

the file is the algorithm used for the color based seganography with multiple compression algorithms

svd分解迭代求取R,T求旋转矩阵求平移矩阵(SVD decomposition iteration for R, T)

说明：  这里有2组图，“1000.0.05”这一组是运行结果比较好的一组图，但是当时修改了时间间隔而没有改坐标说明，所以db1000.0.05.fig这幅图的坐标说明后来做了人工改正（应该是“time(0～250ms分成5000组,步长0.05ms”）。(Reuters, "1000.0.05" This group is running a relatively good results Reuters. But then amended the time interval and not changed coordinates Note So db1000.0.05.fig site map coordinates statement later became the artificial correction (should be "ti me (0 ~ 250ms group into 5000, 0.05 Step ").)
