A Image Dehazing Algorithm Combined with Al-Alaoui Operator and Improved Dark Channel
Aiming at the problems of limited effect,halo effect and color distortion in traditional image dehazing methods,a priori dehazing algorithm combined with Al-Alaoui operator and improved dark channel is proposed in this paper.Firstly,Al-Alaoui operator is used to enhance the image by convolution filtering,then the improved quadtree search method is used to estimate the atmospheric light,and the guided filter is used to refine the medium transmittance.Finally,the enhanced image is restored using the optimized atmospheric light value and transmittance.After comparative analysis,the new algorithm has obvious improvement in both subjective and objective aspects.
