在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

光通信新技术的简介：光接收机和光检测机的详细讲解好描述。(optics fiber communications)

主要根据回声路径的改变来判断是否发生了双端通话，对研究算法的同学具有一定的参考价值。(A double-ended conversation about the detection of foreign literature, mainly based on changes in the echo path to determine whether there has been double-ended conversation, students study algorithm has a certain reference value.)

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解， 以说明三种取阈值方法和三种噪声标志对去噪性能的影响。(This procedure Mr. Cheng a " Blocks" signal, and then adding white Gaussian noise, and then ' db3' wavelet decomposition, to illustrate the three kinds of check-threshold method and three kinds of noise, signs of de-noising performance.)

给灰度图加入白噪声和椒盐噪声，并设计了几种去噪的算法实现对噪声的降低(Adding white noise to the grayscale and salt and pepper noise, and designed several denoising algorithm for noise reduction)
