数字图像处理摘要中英文.doc

摘 要图像是对客观对象的一种相似性的、生动性的描述或写真。根据图像空间坐标和明暗程度的连续性的不同，图像可分为数字图像和模拟图像两大类。图像处理可分为模拟图像处理和数字图像处理两种方式。利用可视化软件编制一个数字图像增强处理系统，实现图像的读取和显示，实现图像常用增强算法，就是本次毕业设计的目的。本文介绍了Visual C+高级语言编程，图像处理，数字图像增强技术、及其各种算法的基本知识。作者根据几种常用算法，编制了数字图像增强处理系统1.0，在Visual C+下编译执行，读入图象文件后出现相应菜单和工具条，根据其执行即可。此系统在Windows操作环境上通过，得到较满意的结果。本文最后列出了几种常用算法的源代码和实现算法后的效果图，并对算法的优缺点进行了分析。关键词：数字图像增强，空间域，频率域，直方图，VC+ ABSTRACTImage seems to be a kind of homogeneous and vivid description to the impersonal object. According to the coordinates and the continuity of its clear and dark degree are different, image can be divided into two types with the digital image and the analog image. Image processing also can be divided into the analog image processing and the digital image processing two kinds of methods. Make use of the visualization software to compile a digital image enhancement system, and realize to read of image with display, and realize the algorithm that image enhancement in common use, is the graduation design purpose. This graduation thesis introduced the Visual C+ high language, image processing, and the digital image enhancement technique, and some kinds of algorithms basic knowledge. According to some common algorithm, the author compiled a system to use for accomplishing the digital image enhancement. It translates and edits to execute under the Visual C+. After the image file be read into the system, it will display the right menu and toolbar, according it to carry out. This system has passed, got the satisfied result on the Windows operating environment. This text finally listed the source code of some common algorithm and the picture that have realized the algorithm. Combined advantage and weakness towards the algorithm to proceed the analysis.KEYWORDS: di
