基于Matlab的数字图像处理课程设计报告.doc

课程设计(论文)说明书 题 目： 数字图像处理的MATLAB实现  摘 要 利用matlab的GUI程序设计一个简单实用的图像处理程序。该程序应具备图像处理的常用功能，以满足用户的使用。现设计程序有以下基本功能： 1.图像的读取和保存。 2.设计图形用户界面，让用户能够对图像进行任意的亮度和对比度变化调整，显示和对比变换前后的图像。 3.设计图形用户界面，让用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域。 4.编写程序通过最近邻插值和双线性插值等算法将用户所选取的图像区域进行放大和缩小整数倍的操作，并保存，比较几种插值的效果。 5.图像直方图统计和直方图均衡，要求显示直方图统计，比较直方图均衡后的效果。 6.能对图像加入各种噪声，并通过几种滤波算法实现去噪并显示结果。 关键词:图像；截图；缩放；直方图；加噪去噪 Abstract Use of matlab GUI programming a simple and practical image processing program. The program should have the common use of the image processing function, to meet the users use. Now has the following basic function design program: 1. The image of the reading and save. 2. The graphical user interface design, to enable users to the image of any brightness and contrast change adjustment, display and contrast transform the before and after images. 3. The graphical user interface design, let users can use the mouse to select the image the interested region, display and save the for the area. 4. Write a program through the nearest interpolation and double linear interpolation algorithms such as the selection of users will enlarge image region and narrowing the integer times the operation, and preserve, the comparison of several interpolation effect. 5. The image histogram statistics and histogram equalization, required to display histogram statistics, compared the effect after the histogram equalization. 6. Can join various noise image, and through several filtering algorithm denoising and displays the results. Keywords：Image,；screenshots； zoom； histogram,；add noise to noise 目 录 引言 …………………………………………………………………………4 1 界面展示……………………………………………………………………………4 2 具体设计……………………………………………………………………………5 2.1 菜单设计……………………………………………………………………………5 2.2 图像基本处理………………………………………………………………………5 2.2.1图像旋转……………………………………………………………………… 2.2.2截图…………………………………………………… …………………… 2.2.3亮度调节……………………………………………………………………… 2.2.4灰度图像……………………………………………………………………… 2.3 加噪和去噪…………………………………………………………………………7 2.3.1加入噪声……………………………………………………………………… 2.3.2滤
