数字图像处理毕业设计

数字图像处理毕业设计【篇一：本科毕业设计——c++数字图像处理】本科毕业设计（论文）摘要几何变换是最常见的图像处理手段，通过对变形的图像进行几何校正，可以得出准确的图像。常用的几何变换功能包括图像的平移、图像的镜像变换、图像的转置、图像的缩放、图像的旋转等等。目前数字图像处理的应用越来越广泛，已经渗透到工业、航空航天、军事等各个领域，在国民经济中发挥越来越大的作用。作为数字图像处理的一个重要部分，本文介绍的工作是如何用visualc++编程工具设计一个完整的应用程序，实现经典的图像几何变换功能。程序大概分为两大部分：读写bmp图像，和数字图像的几何变换。即首先用visualc++创建一个多文档应用程序框架，在实现任意bmp图像的读写，打印，以及剪贴板操作的基础上，完成经典的图像几何变换功能。图像几何变换的visualc++编程实现，为校内课题的实现提供了一个实例。关键字：图像处理；几何变换；bmp图像；visualc++abstractthegeometricaltransformationisthemostpopularimageprocessingmethod.wecangetanexactimagefromadistortedimagethroughthegeometricalemendation.thetransformingmethodsincommonuseincludingtranslation,mirror,rotation,ortransposeanimage.sincethedomainofdigitalimageprocessingapplicationhasbecomingwiderandwider,itpenetratesintomanyfields.suchasindustry,aviation,military,andhasbecomemuchmoreimportantineveryaspectsofourlife.beinganimportantpartofdigitalimageprocessing,theworkintroducedinthisarticleisabouthowtodesignanintegratedapplicationprogramusingvisualc++toimplementtheclassicgeometricaltransformation.theprogramcanbedividedintotwoparts:readorwriteabmpimage,andthegeometricaltransformationforit.soidesignedamultipledocumentinterfacefirst,onthebasicofread,write,print,andtheclipboardoperationofanimage,thencarryoutthefunctionofgeometricaltransformationfinally.theimplementationofgeometricaltransformationusingvisualc++isagoodexampleforcarryingoutintramuralproblems.keywords:imageprocessing;geometricaltransformation;bmpimage;visualc++目录第一章绪论........................................................................................................................................................11．1何谓数字图像处理.................................................................................................................................11．1．1图像的概念..................................................................................................................................11．1．2图像处理.......................................................................................................................................11．2图像处理学的内容和其他相关学科的关系.........................................................................................21．2．1图像处理学的内容......................................................................................................................21．2．2图像处理学与相关学科的关系..................................................................................................21．3数字图像处理的特点及其应用.............................................................................................................21．3．1数字图像处理的特点..................................................................................................................21．3．2数字图像处理的应用..................................................................................................................31．4visualc++.............................................................................................................................................41．4．1visualc++简述.............................................................................................................................41．4．2将visualc++应用于数字图像的几何变换...............................................................................4第二章数字图像处理的基本概念....................................................................................................................52．1图像和调色板.........................................................................................................................................52．1．1图像的显示..................................................................................................................................52．1．2调色板..........................................................................................................................................52．1．3色彩系统......................................................................................................................................62．1．4灰度图..........................................................................................................................................72．2gdi位图.................................................................................................................................................72．2．1从资源中装入gdi位图.............................................................................................................82．2．2伸缩位图......................................................................................................................................82．3设备无关位图（dib）..........................................................................................................................82．3．1bmp文件中dib的结构.............................................................................................................92．3．2dib访问函数.............................................................................................................................112．3．3使用dib读写bmp文件.........................................................................................................12第三章图像的
