Abstract
With the ever-growing availability of Virtual Reality (VR) products, the 360-degree video has a widespread application prospect, which also brings new challenges to its quality assessment. Considering its unconventional display environment, the users’ attention on 360-degree video may be significantly different from its conventional 2D version. Recently, the Weighted-to-Spherically-uniform Peak Signal-to-Noise Ratio (WS-PSNR) was developed to weight PSNR by its covered area in 360-degree video display. In this work, we find that the average attention per area still differs subject to its latitude. Thus we propose to utilize this average attention to formulate a latitude-based quality weight matrix. Through experiments, this new matrix outperforms that of WS-PSNR in pooling of PSNR when latitude-based quality fluctuations exist in 360-degree video display.
