Polarimetric dehazing methods have shown advantages of excellent detail recovery capacity and color restoration. To improve the dehazing capacity of polarimetric dehazing methods, we propose a new polarimetric dehazing method. It utilizes discrete cosine transform to construct the image pyramid and then build the Laplacian pyramid. Each level of the Laplacian pyramid is dehazed by the polarimetric dehazing method, and the dehazed image is reconstructed from the handled Laplacian pyramid. The experiment results show that compared with the traditional polarization optical dehazing method, the proposed method can achieve the comparable or better dehazing images, and shows good dehazing capacity. The proposed method is significant for the further improvement of polarimetric dehazing method.
