Research Progress of Infrared and Visible Image Fusion Algorithms

Abstract

Infrared images are easy to identify thermal targets,and visible images have rich texture information.The fusion of infrared and visible images takes the advantages of both optical bands which can clearly show the targets and background.It has been widely used in many fields such as military reconnaissance,security monitoring,remote sensing measurement,and becomes a key research direction in the field of image fusion.In recent years,infrared and visible image fusion algorithms have attracted the attention of researchers around the world and have been studied abundantly.In this paper,the image fusion algorithms are introduced firstly,including traditional image processing methods of multi-scale transformation,sparse representation,and deep lear-ning algorithms based on CNN,GAN,AE.Then,the evaluation methods of fusion images are summarized,and a variety of common objective evaluation indexes are classified.After that,comparative experiments are carried out to subjectively evaluate and quantitatively analyze the advantages and disadvantages of these algorithms.Finally,the development trend of infrared and visible image fusion methods is prospected.
