数字图像处理实验四、基于GUIDE的图像处理软件开发.docx

实验四、基于GUIDE的图像处理软件开发一、 实验目的（1） 学习使用MATLAB GUIDE的基本操作。（2） 以图像增强为例完成基本图像处理功能的回调函数编写。二、 实验主要仪器设备（1） 台式机或笔记本电脑。（2） MATLAB软件（含GUIDE开发环境）。三、 实验原理（1） 基于灰度直方图变换的图像增强。（2） 灰度修正图像增强。（3） 图像平滑滤波。（4） 图像锐化处理。四、 实验内容（1） 直方图的计算及用直方图均衡原理增强图像。（2） 线性灰度变换图像增强。（3） 对受椒盐噪声污染的图像采用低通处理模板去燥。（4） 对受椒盐噪声污染的图像采用中值滤波去噪。（5） 对图像采用梯度算子和拉普拉斯算子进行锐化。五、 实验步骤（1） 建立开发环境。（2） 编写相关回调函数。（3） 不断调试、优化，获得较满意的人机交互效果。六、 实验程序function varargout = 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*. Starting from the left, property value pairs are% applied to the GUI before test4_OpeningFcn gets called. An% unrecognized property name or invalid value makes property application% stop. All inputs are passed to test4_OpeningFcn via varargin.% *See GUI Options on GUIDEs Tools menu.
