[image fusion] image fusion based on pseudo Wigner distribution (PWD) with matlab code

1 brief introduction

A method based on pseudo Wigner distribution is proposed (PWVD) Fusion method . Using one dimension N Sliding windows of pixels in all directions Perform pseudo Wigner transform on each image to be fused , Select the direction with the largest root mean square as the direction of each image to be fused PWVD Decomposition direction , The energy spectrum of different frequency bands of the image to be fused is decomposed , then , For each to be integrated Energy spectrum of the same frequency band , The fusion principle is to maximize the regional energy in the high frequency band , The energy variance in the low frequency band is the largest , Form a fusion energy spectrum with different frequency bands , Last , The energy spectrum is analyzed PWVD inverse transformation , formation Fusion images . For infrared and visible light images , Multi focus image , electronic computer X X-ray tomography (CT) Image and magnetic resonance (MR) Image and infrared and synthetic aperture radar (SAR) The image is fused Examination , The information entropy between the fused image and the image to be fused is compared . Experimental results show that , The fused image using this algorithm retains most of the information of the image to be fused .

function varargout = mapfusion(varargin)% MAPFUSION M-file for mapfusion.fig%      MAPFUSION, by itself, creates a new MAPFUSION or raises the existing%      singleton*.%%      H = MAPFUSION returns the handle to a new MAPFUSION or the handle to%      the existing singleton*.%%      MAPFUSION('CALLBACK',hObject,eventData,handles,...) calls the local%      function named CALLBACK in MAPFUSION.M with the given input arguments.%%      MAPFUSION('Property','Value',...) creates a new MAPFUSION or raises the%      existing singleton*.  Starting from the left, property value pairs are%      applied to the GUI before mapfusion_OpeningFunction gets called.  An%      unrecognized property name or invalid value makes property application%      stop.  All inputs are passed to mapfusion_OpeningFcn via varargin.%%      *See GUI Options on GUIDE's Tools menu.
