Fast haze removal algorithm using dark channel prior
Chen Jian-pen · Jisuanji gongcheng yu sheji · 2014
To recover degraded images due to the atmosphere particles absorbing and scattering the light,the dark channel prior algorithm received good results in image removal,but soft matting algorithm was computational complex and quite time-consuming. The advantages and disadvantages of the existing defogging algorithms were analysed,based on which a new fast defogging algorithm using dark channel prior was proposed which firstly used the white balance and then used trilateral filter to obtain an edge-preserving dark channel image,thus the scene albedo was recovered. Experimental results proved that this algorithm was low in complexity and could effectively remove haze from a foggy image with a little time.
