层次分析法（Analytic Hierarchy Process，简称AHP）是将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。该方法是美国运筹学家匹茨堡大学教授萨蒂于20世纪70年代初，在为美国国防部研究"根据各个工业部门对国家福利的贡献大小而进行电力分配"课题时，应用网络系统理论和多目标综合评价方法，提出的一种层次权重决策分析方法。(AHP (Analytic Hierarchy Process, referred AHP) is always the element of the decision-making related to broken down into goals, guidelines, programs and other levels, on this basis for decision-making qualitative and quantitative analysis. This method is the U.S. Operations Research Professor at the University of Pittsburgh Satie early 1970s, the U.S. Department of Defense for research, " according to various industrial sectors contribution to national welfare and power sharing" topic, application network systems theory multi-objective and comprehensive evaluation methods, the right to propose a hierarchical weight decision analysis methods.)

Atmel抯 AVR controller offers an Analog to Digital Converter with 10-bit resolution.
In most cases 10-bit resolution is sufficient, but in some cases higher accuracy is
desired. Special signal processing techniques can be used to improve the
resolution of the measurement. By using a method called 慜versampling and
Decimation?higher resolution might be achieved, without using an external ADC.
This Application Note explains the method, and which conditions need to be
fulfilled to make this method work properly

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.)
