摘要
本次课题是通过对三维重建中的图像进行预处理,去除或抑制图像噪声,提高图像的质量。利用VC++,可继承、封装、移植等成熟的软件技术,对数字图像进行处理,实现图像灰度均衡、图像平滑、中值滤波、图像锐化等功能。实验表明,该软件可以快速、准确的对BMP格式的灰度图像进行处理,达到使图像对比度增强、平滑或锐化,从而改善图片质量或增强图像中的边缘信息的目的,为三维重建提高精度做好准备。
本文在第一章绪论中介绍了数字图像预处理的发展情况,数字图像预处理的应用以及设计研究内容。在第二章中介绍了数字图像的基础内容,包括数字图像预处理的术语、调色板、灰度图等数字图像的基础知识。第三章对Visual C++做一个简介。在第四章中介绍了程序的设计思想以及数字图像预处理的原理。包括图像的灰度均衡、图像平滑、中值滤波、图像锐化等。其中图像平滑化处理包括图像平滑和中值滤波两种方法;图像锐化包括梯度锐化和拉普拉斯锐化两种方法。各功能的原理介绍完都有相关的功能示意图。可以对各功能的原理及效果有一个清楚的了解。第五章介绍了各功能实现的流程,包括程序运行界面及各功能运行界面。
关键词:数字图像处理;Visual C++;图像增强
Abstract
The subject is three-dimensional reconstruction of the image pre-processing, to remove or suppress image noise and improve image quality. VC + + to implement the use of high efficiency, inheritable, packaging, transfer software, such as mature technology, digital image processing to achieve a balanced gray-scale images, image smoothing, median filtering, image sharpening and other functions. The experiments show that the software can be quickly and accurately to the BMP format to deal with gray-scale images to the image contrast enhancement, smoothing or sharpening to improve the picture quality or enhance the image of the edge of the purpose of information for the three-dimensional reconstruction to improve prepare accuracy.
Introduction In the first chapter of this article described the development of digital image pre-processing, the digital image pre-processing of applications, and design research. In the second chapter describes the basis of digital image content, including digital image pre-processing terms, Palette, grayscale, such as basic knowledge of digital imaging. Chapter III of the Visual C + + to make a profile. In the fourth chapter describes the design thinking process as well as the principle of pre-processing digital images. Including the gray balanced image, image smoothing, median filtering, image sharpening and so on. Which image processing including image noise smoot
