Abstract

Objective quality assessment plays a vital role in the evaluation and optimization of panoramic video. However, most of the current methods only consider the structural distortion caused by the projection format, and do not consider the effect of clarity on quality evaluation. For this reason, we propose a new objective video quality assessment method for panoramic video. First, the source image and the distorted image are down-sampled to obtain five sets of images with different scales. Second, calculate WS-SSIM at different scales. Finally, according to the degree of influence of different scales on the subjective evaluation, different coefficients are assigned to the corresponding WS-SSIM, and the overall score is calculated. Experiments on the database established in our laboratory have proved its effectiveness through comparison.
