基于人眼视觉特性的红外图像细节增强
Infrared image enhancement based on human visual properties
摘要
Abstract
Limited by the mechanism of infrared imaging and the detector,infrared images have the disadvantages of low con-trast and blurry edge.These shortcomings lead infrared image unsuitable to be observed by both human and computer.This arti-cle proposed a new method that combined the layering idea with the human visual properties to enhance the infrared image.The proposed method relied on bilateral filtering to separate a base component,which contained the large amplitude signal and must be compressed,from a detail component,which must be expanded because it contained the small signal variations related to fine texture.The base component was mapped into the proper range which was 8 bit using the human visual properties,and the de-tail component was applied the method of adaptive gain control.Finally,it recombined and quantized the two parts to 8 bit do-main.Experimental results show that this algorithm exceeds most current image enhancement methods in solving the problems of low contrast and blurry detail.关键词
