Abstract:
In this paper, we examine the presence of forward and backward temporal masking in video when the stimulus is a burst of frozen frames and the mask is a scene change. We assess the impact of frame freezing impairment on the perceived video quality using a variety of source content and freezing events of different durations placed at different locations in the video. Our experimental results indicate the existence of an asymmetrical temporal masking effect with a more significant backward masking than forward masking. However the overall impact of temporal masking on visual quality was measured to be relatively weak. Implications for video coding are also discussed.
