根据)EF 特性中的对比度敏感度， 即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮 度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作 为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)

用Matlab编程，实现解决该问题的单样本训练BP网络，设置一个停止迭代的误差Emin和最大迭代次数。在调试过程中，通过不断调整隐层节点数，学习率η，找到收敛速度快且误差小的一组参数。产生均匀分布在区间[-4，4]的测试样本，输入建立的模型得到输出，与Hermit多项式的期望输出进行比较计算总误差（运行5次，取平均值）(Using Matlab programming, to solve the problem of single sample training BP network, set a stop error iterations Emin and the maximum number of iterations. In the debugging process, by continuously adjusting the hidden layer nodes, learning rate η, fast convergence and find a set of parameters small errors. Produce a uniform distribution in the interval [4,4] of the test sample, the model has been established input output with the expected output Hermit polynomial calculated by comparing the total error (run 5 times the average))

运用matlab语言描述小波分析在信号处理中的应用。(Based on matlab signal processing of wavelet analysis.)

本文首先介绍了边缘的定义，说明了传统的几种边缘检测算子并比较了它们算法的不同与优缺点。随后引入了小波的思想、小波的基本概念， (This paper introduces the edge of the definition, Note some of the traditional edge detection operators and compare them with the different algorithms advantages and disadvantages. The subsequent introduction of wavelet thinking, wavelet the basic concepts,)
