浙江万里学院图像增强综合应用研究姓名：学号：专业：电子信息工程指导老师：20160615摘要图像增强是图像处理的一项重要内容，其目的是将图像中感兴趣的部分尽可能地突现出来。在一个图像系统中，图像的获取、发送、传输、接收、输出、复制等等，每一个环节都会产生干扰，都会使图像质量降低。因此，如何对这些“降质”图像进行处理使其达到我们的要求已受到研究人员的高度重视。传统的图像增强算法在改善图像的对比度和增强图像的细节的同时也放大了噪声,这是传统算法的缺点和不足之处。【关键词】图像处理；图像增强；算法研究。Abstract：Imageenhancementisanimportantpartofimageprocessing,itspurposeistopartinterestintheimageasmuchaspossibletothefore.Inanimagesystem,imageacquisition,sending,transmitting,receiving,export,copy,andsoon,everystepwillinterferewiththeimagequalitywillbereduced.Therefore,howthese"lowerquality"imageprocessingtomakeitmeetourrequirementshasbeenattachedgreatimportancetoresearchers.Traditionalimageenhancementalgorithmswhileimprovingimagecontrastandimagedetailenhancementalsoamplifiednoise,whichisattheshortcomingsanddeficienciesofthetraditionalmethod.目录1绪论..................................................................................................................1.1课题背景及意义.....................................................................................1.2研究现状及课题主要内容.....................................................................1.3本文的工作结构.....................................................................................2图像增强的基本理论........................................................................................2.1图像增强的定义.....................................................................................2.2数字图像的基本概念.............................................................................2.2.1数字图像的表示..........................................................................2.2.2图像的灰度变换..........................................................................2.2.3灰度直方图..................................................................................2.3本章小结.................................................................................................3图像增强的算法分析........................................................................................3.1直方图均衡化.............
