PAGE   PAGE \* MERGEFORMAT 39 中文摘要 随着技术的发展和人们生活水平的不断提高，数字图像作为记录和传达信息的一种媒介，在人们生活和生产中扮演者越来越重要的角色。随着数字图像的不断进步发展和成熟，数字图像不仅在日常生活的摄影，平面设计，传媒发挥自己的作用，也会更多地在航天航空，刑事侦查，精密医疗仪器等更加重要的研究领域起到更大的作用。于是，不断学习和探索各种数字图像处理技术，对准确运用各种数字图像更好地服务于生产生活，愈发显得重要。 而数字图像边缘增强是数字图像处理技术里面重要的一种，是一种提高图像清晰度的重要方法之一。 经实例检测，该图像边缘增强算法可以有效提高图像的清晰度，同时有效避免图像噪点的增强。 关键词：数字图像，边缘增强，清晰度 ABSTRACT With the development of technology and peoples living standard, as a way of recording and conveying information, digital images play an important rolein peoples daily life and production. with the development and maturity of digital image, digital imagesare not only applied in photography, graphic design, media, but alsoplay a greater role in aerospace, criminal investigation, precision medical instruments or other important fileds.In this case, learning and exploration of the processing techniques of digital image, and how to use various digital images properly to serve forour daily life and production, arebecoming more and more important. As we all know,the digital image edge enhancement is one of the most important digital image processingtechnology,which is an inportant approach to improve the image definition. After testing, the algorithm of image edge enhancement can effectively improve the clarity of image, and effectively avoid the enhancement of image noise. Key Words：digital image，enhancement of image edge，clarity 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc384718324 第一章 导论  PAGEREF _Toc384718324 \h 4  HYPERLINK \l _Toc384718325 1.1 课题背景  PAGEREF _Toc384718325 \h 4  HYPERLINK \l _Toc384718326 1.2 课题意义  PAGEREF _Toc384718326 \h 4  HYPERLINK \l _Toc384718327 1.3 研究内容方法步骤  PAGEREF _Toc384718327 \h 5  HYPERLINK \l _Toc384718328 1.4 论文的创新  PAGEREF _Toc384718328 \h 5  HYPERLINK \l _Toc384718329 第二章 图像边缘检测  PAGEREF _Toc384718329 \h 6  HYPERLINK \l _Toc384718330 2.1 图像边缘检测方法概述  PAGEREF _Toc384718330 \h 6  HYPERLINK \l _Toc384718331 2.2 Roberts边缘检测  PAGEREF _Toc38471833
