Abstract: Objective To overcome the problem of a degraded image due to the reduction of contrast under hazyweather,according to the differing polarization characteristics between the target scene and atmos-pheric aerosol,we researched image restoration for target recognition based on polarized detectionthrough haze.To obtain different polarized orientation images by experiment during hazy weather,weproposed an image restoration algorithm to enhance the image contrast,to remove degradation fromhaze on images.Experimental results show that this algorithm can effectively enhance image contrastand entropy as well as recover the target.As a by product,the method yields a range map of thescene.This research provides an effective method for the target recognition under hazy weather conditions.
