​1 简介

文章从人的视觉系统出发提出一 种新的基于HSI空间伪彩色异类多传感器图像融合方法,可以用于解决异构多传感器的图像融合问题,在HSI色彩空间可以大大简化图像分析和处理的工作量. 图像融合仿真实验充分验证了该方法可以帮助在人眼和机器识别下克服了由RGB空间伪彩色法造成的融合图像分辨率的下降,同时保留了异类传感器的完整信息, 仿真实例证明该算法得到的融合图像的灰度图像其空间分辨率,该算法利于人眼的判读和机器的识别,具有较大的应用价值.

function varargout = resolutionmerge(varargin)

% RESOLUTIONMERGE M-file for resolutionmerge.fig

%      

% GUI for improving resolution of lower resolution image using higher

% resolution image using RGB-to-HSI conversion.

% Images have to be spatially registered.

%

% Monochromatic (gray scale) low resolution image is converged to colored

% image by false color mapping to "hot" color scheme. This RGB image is

% then converted to Hue, Saturation and Value (HSV) image. Value component is replaced

% by higher resolution image and the resulting HSV image is converted back to

% RGB. This RGB merged image converted to gray scale is a merged image with

% improved spatial resolution.

% 

% To run, type:

% >> resolutionmerge

%

% Can work with any type of color or monochromatic image. If images are colored

% they are converted to gray scale first and then merged.

% To load variables from matlab file, the file should contain variables

% LOWRES and HIGHRES
