数字图像处理实验四、基于GUIDE的图像处理软件开发.docxVIP

实验四、基于GUIDE的图像处理软件开发实验目的学习使用MATLAB GUIDE的基本操作。以图像增强为例完成基本图像处理功能的回调函数编写。实验主要仪器设备台式机或笔记本电脑。MATLAB软件（含GUIDE开发环境）。实验原理基于灰度直方图变换的图像增强。灰度修正图像增强。图像平滑滤波。图像锐化处理。实验内容直方图的计算及用直方图均衡原理增强图像。线性灰度变换图像增强。对受椒盐噪声污染的图像采用低通处理模板去燥。对受椒盐噪声污染的图像采用中值滤波去噪。对图像采用梯度算子和拉普拉斯算子进行锐化。实验步骤建立开发环境。编写相关回调函数。不断调试、优化，获得较满意的人机交互效果。实验程序functionvarargout = test4(varargin)% TEST4 MATLAB code for test4.fig% TEST4, by itself, creates a new TEST4 or raises the existing% singleton*.%% H = TEST4 returns the handle to a new TEST4 or the handle to% the existing singleton*.%% TEST4(CALLBACK,hObject,eventData,handles,...) calls the local% function named CALLBACK in TEST4.M with the given input arguments.%% TEST4(Property,Value,...) creates a new TEST4 or raises the% existing singleton*.
