Prof. Alan Bovik and his student Lark Kwon Choi in the WNCG Laboratory for Image and Video Engineering (LIVE) and Prof. Lawrence Cormack in the Center for Perceptual Systems (CPS) in the Department of Psychology study the influence of motion on the visibility of flicker distortions in naturalistic videos.
Video traffic currently comprises more than 50% of all wireless and mobile device data volume. This ratio is expected to increase for years to come. Likewise, deployments of small wireless sensors in the home, factory, retail outlets, automobiles and nearly everywhere else are proliferating. Growth in this space is expected to be exponential for many years to come.
Bandwidth-intensive video streaming applications occupy an overwhelming fraction of bandwidth-limited wireless network traffic. The explosion of video data traffic necessitates new transmission paradigms at different protocol layers that improve video quality of experience, introduce error resilience, and meet quality-of-service (QoS) requirements. Real-time video specifically demands QoS guarantees such as delay bounds for end-user satisfaction. Due to the inherently stochastic nature of wireless fading channels, deterministic delay bounds are difficult to guarantee.
