Eccentricity effect of motion silencing on naturalistic videos

We study the effect of eccentricity on flicker visibility in naturalistic videos. A series of human studies were executed in two tasks ("gaze the fixation mark" and "follow the moving object") to understand how object motion can reduce the visibility of flicker distortions as a function of eccentricity, motion speed, video quality, and flicker frequency. We found that either large eccentricity or large, coherent object motion could reduce flicker visibility. When they are combined, flicker visibility significantly decreased. Flicker visibility remained noticeable even at large eccentricity when the object was static. Human study results and statistical analysis show that highly eccentric, coherent object motion can significantly silence the awareness of flicker distortions on naturalistic videos.
