Abstract:

A novel no-reference video quality assessment model is proposed in order to meet the real-time and low cost requirements of video quality assessment over IP networks. The temporal complexity is calculated without decoding, and the effect of different types of frame loss on video quality is considered. In the proposed model, both spatial and temporal error concealment artifacts of the human visual system (HVS) and frame types are taken into account. Video qualities could be assessed without delay by utilizing the proposed model. Experimental results show that the scores obtained by the proposed model highly agree with the subjective assessment scores. Compared with the video quality evaluation model in G.1070, an average performance gain of 6.96% could be achieved by the proposed model in terms of relativity to subjective results.

Key words: no reference video quality assessment, packet loss, internet video, temporal complexity
