Using Dark Channel Prior to Quickly Remove Haze from a Single Image

Haze is an important influence factor of visible light RS data's obtaining and using.Based on dark channel prior and haze image model,we study the dehaze technology from a single image.Aim at the problem of dark channel prior not work for special region of city image and traditional medium transmission computing method's disadvantage: complex,time-consuming,making use of RS image's characteristics: haze distributes relatively more uniform and depth of field change not acutely,proposes a new quick computing method on the premise of not markedly reduce dehaze effect,to realize single image fast dehaze processing.Using multiple frame images to make system experiment,and do quantitative analysis to dehaze result images' definition.
