摘要得益于数学理论体系的成熟和计算机的，图像处理这门学科也得到了长足的发展。图像处理技术在各个方面都得到广泛的应用，以图像处理技术为基础的图像处理软件也逐渐地走进了大家的视野。现代的图像处理软件大概分为两类：集合了多种功能为一体的综合性软件和针对图像处理某个方面的专业性软件。但是现在数字图像处理技术的发展还有不足，还有很大的提升空间可以发展。

小型图象处理系统设计与实现的目标并不是研究开发一个类似于Photoshop的商业化图像处理软件，本文的目标是在了解数字图像处理基本知识的基础之上实现一个小型的图像处理系统，然后以Visual C++作为编程语言，利用MFC的框架实现设计，自行封装一个针对DIB图像的类，并以此基类派生其他的类来实现具体的功能。用特效显示类来实现图像的扫描显示、滑动显示、渐进显示、马赛克显示。用几何变换类来实现图像的平移、镜像、缩放、旋转。用图像增强类来实现图像的平滑和锐化。用直方图类类来实现图像的直方图均衡化。用数学形态类实现腐蚀和膨胀。用图像分割类实现边缘检测。84509

Abstract The result of mature mathematical theory system and computer and image processing has also been a rapid growth of the subject。 Image processing technology has been widely used in all aspects, on the basis of image processing technology of image processing software is also gradually entered the people field of vision。 Modern image processing software is pided into two categories: probably brings together a variety of functions of an integrated software and on some aspects of the professional image processing software。 But now the development of digital image processing technology and insufficient, there is plenty of room to improve can be developed。

Small image processing system design and realization of the goal is not to the commercialization of research to develop a similar to the Photoshop image processing software, this paper aims to understand the basic knowledge of digital image processing based on the implementation of a small image processing system, and then with Visual C++ as a programming language, using MFC framework design, to encapsulate a DIB image class, and then to the base class derived other classes to implement specific functions。 With special effects show class to implement image scanning display, slide shows, progressive, Mosaic shows。 Using geometric transformation to realize the image translation, image, zoom, rotate。 In image enhancement class to implement image smoothing and sharpening。 Using histogram class to realize the image histogram equalization。 Using mathematical morphology class implements corrosion and expansion。 Use image segmentation class to finish edge detection。
