基于滤波的单幅图像去雾方法
Single Image Dehazing Method Based on Filters
摘要
Abstract
This paper introduces a novel single image dehazing method based on filters.Firstly,in order to maintain a good edge smooth texture,the initial atmospheric scattering light is estimated via bilateral filtering.Then,the initial atmospheric scattering light is refined via the adaptive median filter to keep sharp edges,smooth texture,and actual depth information.Next,the atmospheric light is obtained by the hierarchical searching method of quad-tree subdivision.Finally,the dehazed image is restored by solving the atmosphere attenuation model.Compared with the results obtained by several existing classical dehazing methods,the experimental results show that the dehazed image by our proposed method is closer to the real scene image.Especially,it exhibits obvious superiority in dehazing regions with rich texture and distant scene.关键词
