一、获取代码方式


二、数字图像处理简介

基于matlab GUI数字图像处理平台:8大功能

1 文件操作:读取显示、保存图像、退出;

2 图像编辑:图像缩放、图像滤波、图像剪裁、格式转换、纹理映射;

3 图像分析:像素选择、强度描述图、图像轮廓图、绘制直方图;

4 图像调整:直方图均衡化、直方图规定化、去背景、阙值化、灰度变换;

5 图像平滑:加噪、中值滤波、低通滤波、图像复原;

6 图像锐化:梯度法、Sobel算子滤波、拉氏算子滤波、空域高通滤波、频域高通滤波;

7 图像高级处理:边缘检测、图像分割;

8 小波变换:1次小波分解、2次小波分解、第1层小波重构、第2层小波重构;

三、部分源代码

unction varargout = cml20062036(varargin)
%CML20062036 M-file for cml20062036.fig
% CML20062036, by itself, creates a new CML20062036 or raises the existing
% singleton*.
%
% H = CML20062036 returns the handle to a new CML20062036 or the handle to
% the existing singleton*.
%
% CML20062036('Property','Value',...) creates a new CML20062036 using the
% given property value pairs. Unrecognized properties are passed via
% varargin to cml20062036_OpeningFcn. This calling syntax produces a
% warning when there is an existing singleton*.
%
% CML20062036('CALLBACK') and CML20062036('CALLBACK',hObject,...) call the
% local function named CALLBACK in CML20062036.M with the given input
% arguments.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
