【图像处理基础】图像局部放大【含Matlab GUI源码 1016期】
作者:互联网
一、简介
基于matlab GUI图像局部放大
二、源代码
function varargout = piczoom(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @piczoom_OpeningFcn, ...
'gui_OutputFcn', @piczoom_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
if nargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end
if nargout
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
gui_mainfcn(gui_State, varargin{:});
end
function piczoom_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
%m为图片的纵向像素数,n为图片的横向像素数,mapData为修正后的图像数据
global m n mapData
%读取图片到主坐标轴axes1
axes(handles.axes1);
cData = imread('pic1.jpg');
hImage = image(cData);
axis off;
%设置当前坐标轴为右上角的小坐标轴axes2
axes(handles.axes2);
%初始化全局变量m和n
m = size(cData, 1);
n = size(cData, 2);
%扩展图片数据,使得鼠标在图片边缘附近时,不至于出错
mapData = 255 * ones(m+40, n+40, size(cData, 3), 'uint8');
mapData(21:m+20, 21:n+20, :) = cData;
%将图片数据存到handles结构体中
handles.hImage = hImage;
%更新handles
guidata(hObject, handles);
function varargout = piczoom_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;
function figure1_WindowButtonMotionFcn(hObject, eventdata, handles)
global m n mapData
%获取鼠标当前所在的点
pos = get(handles.axes1, 'CurrentPoint');
posX = pos(1, 1);
posY = pos(1, 2);
%若鼠标在坐标轴区域内,更新小坐标轴axes2
三、运行结果
四、备注
