说明： 基于压缩感知思想的图像分块压缩与重构方法
考虑到大多数图像信号信息分布有差异, 编码端, 在对图像分块的基础上, 融合熵估计
和边缘检测方法计算各图像块的信息含量, 再从两个不同的角度进行分类采样: 依据信息量多少将图像块分为平滑、过渡和纹理3 类, 使用不同的采样率采样 依据信息量的分布特征, 采用不同的采样率分配策略进行采样. 在解码端, 根据不同类型的图像块构造不同的线性算子进行重构, 再运用改
进的迭代阈值算法去除块效应和噪声. 实验证明, 算法在提升图像重构质量的同时缩短了重构时间,并且对纹理边缘多的图像的重构效果较其他方法理想.(Considering that most information of the image signal difference distribution, the encoding side, in the right image sub-blocks based on the integration entropy estimation
And edge detection method for calculating the information content of each image block, and two different angles classification sampling: The number of image blocks based on the amount of information into a smooth, transition and texture three classes, using different sampling rates based on the amount of information distribution characteristics, using different sampling sampling rate allocation strategy. in the decoding side, depending on the type of image blocks to construct different linear operator reconstructed, re-use change
Iterative thresholding algorithm into blockiness and noise removal experiments show image reconstruction algorithm to enhance the quality while reducing reconfiguration time, and much of the texture edge image reconstruction results are satisfactory compared to other methods.)

Order-disorder
有序无序转变的计算机模拟——MC算法
一个样品做实验，从低温有序相，逐渐升温，到高温无序相。
模型假设：
1 模拟三维简单斜方，AB型合金，共有M*N*L个原子；
2 最邻近假设，即只考虑最邻近原子之间的相互作用，次邻近和更远的原子之间的作用忽略（误差较大），
，在简单斜方中，最邻近原子数z=6；
3 只考虑势能的作用，AA，BB，AB原子间的作用用Eaa,Ebb,Eab=Eba表示 且忽略振动能（原则上，温度很高时，不能忽略）等；
4 各原子之间的相互作用独立，即各化学键相互独立；
5 边界原子任然周期排列，只不过，邻近原子数减小，能量较高；边界面上的原子z=5；线
上的原子z=4，顶点上的原子z=3；由于顶点上只有四个原子，算法中不考虑这种情况；
6 其它假设。( Order-disorder transition of computer simulation- MC algorithm a sample experiment, from the low-temperature ordered phase, gradually warming up to a high temperature disordered phase. Model assumes that: 1 of three-dimensional rhombic, AB-type alloy, a total of M* N* L atoms 2 nearest the assumption that only consider the interaction between the neighboring atoms, and further sub-adjacent atoms ignore the interaction between the (larger error), , in the simple oblique Fang, nearest neighbor atoms, z = 6 3 only consider the potential role, AA, BB, AB interatomic with Eaa, Ebb, Eab = Eba representation and ignore the vibration energy (principle, the temperature is high, it can not be ignored), etc. 4 each atom interactions between independent, which means that each bond independently 5 boundary periodic arrangement of atoms in any course, but , adjacent atoms decreases, the higher energy boundary atomic plane z = 5 atoms on line z = 4, the vertex atoms z = 3 only four)
