Zusammenfassung | In this paper, a novel no-reference method to predict the impact of packet losses in video sequences on visual attention is proposed. Initially, the results of a subjective eye-tracking experiment are analyzed to determine whether the artefacts caused by network degradations result in abrupt saliency changes. Then, the proposed method employs existing objective visual attention models to compute the saliency maps of the individual frames. Subsequently, the temporal consistency of the saliency maps is investigated and correlated with the error propagation pattern that results from the packet losses to predict visual saliency changes in a rule-based approach. Experimental results on a proprietary database are presented to demonstrate the validity of the proposed method. |
