摘 要 MATLAB，数字图像处理图像增强 Abstract Digital image processing is an emerging technology, with the development of computer hardware, real-time digital image processing has become possible due to digital image processing algorithms to appear, making it faster and faster processing speed, better for People services .Digital image processing is used by some algorithms computer graphics image processing technology. Digital image processing technology has been in various areas have a relatively wide range of applications. Image processing large amount of information on the processing speed requirement is relatively high. MATLAB powerful computing and graphics display capabilities, so that image processing becomes more simple and intuitive. This paper introduces characteristics of MATLAB language and this MATLAB-based digital image processing environment, describes how to use the MATLAB Image Processing Toolbox for its digital image processing, and through some examples to illustrate the use of MATLAB Image Processing Toolbox for image processing method. Mainly discusses the use of MATLAB for image enhancement. Key words：MATLAB,igital?image?processing,? image?enhancement. 目 录 摘要 I 2 数字图像增强处理方法简介 5 2.1 基本概念 6 2.2 图像增强处理方法 7 3 MATLAB基本知识介绍 7 3.1 MATLAB的概述 7 3.2 MATLAB产生的历史背景 7 3.3MATLAB语言的特点........................................................................... 3.4MATLAB 在图像处理中的应用........................................................... 4 图像增强 9 4.1 空域变换增强 9 4.1.1增强对比度 4.1.2 图像求反 4.2 空域滤波增强 9 4.2.1 基本原理 4.2.2 线性平滑滤波器 4.2.3 非线性平滑滤波器 4.2.4 线性锐化滤波器 4.3 频域增强 4.3.1 基本原理 4.3.2 低通滤波 4.3.3 高通滤波 5 二值图像分析 5.1 引言 5.2 二值形态学的基本运算 5.2.1 膨胀 5.2.2 腐蚀 5.3 二值分析进行图像处理综合应用 5.3.1 噪声滤除 5.3.2 边界提取 6 总结与展望 6.1 总结 6.2 展望 致 谢 14 参考文献 15 附 录 16 一级标题用加黑四号宋体二级标题用小四宋体 1 绪论 本章简略介绍课题的研究目的及意义，该课题国内外研究现状以及论文内容安排等。 1.1 课题研究目的及意义 数字图像处理（Digital Image Processing），就是利用数字计算机或者其他数字硬件，对从图像信息转换而得到的电信号进行某些数学运算，以提高图像的实用性。例如从卫星图片中提取目标物的特征参数，三维立体断层图像的重建等。总的来说，数字图像处理包括点运算、几何处理、图像增强、图像复原
