【图像融合】基于小波变换算法实现图像融合matlab代码

1 简介

提出了一种基于小波变换的融合算法,算法针对小波变换后的低频分量和高频分量的不同特点,选用了不同的准则进行融合,通过小波逆变换得到融合图像.实验结果表明,这种算法充分考虑了小波变换的特点和人眼视觉特性,具有增强图像的空间细节能力,融合效果良好.

2 部分代码

function varargout = MainForm(varargin)

% MAINFORM MATLAB code for MainForm.fig

%     MAINFORM, by itself, creates a new MAINFORM or raises the existing

%     singleton*.

%

%     H = MAINFORM returns the handle to a new MAINFORM or the handle to

%     the existing singleton*.

%

%     MAINFORM('CALLBACK',hObject,eventData,handles,...) calls the local

%     function named CALLBACK in MAINFORM.M with the given input arguments.

%

%     MAINFORM('Property','Value',...) creates a new MAINFORM or raises the

%     existing singleton*. Starting from the left, property value pairs are

%     applied to the GUI before MainForm_OpeningFcn gets called. An

%     unrecognized property name or invalid value makes property application

%     stop. All inputs are passed to MainForm_OpeningFcn via varargin.

%

%     *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

%     instance to run (singleton)".
