Abstract

The possibility of perceptual compression using live eye tracking has been anticipated for some time by many researchers. Among the challenges of real-time eye-gaze-based perceptual video compression are how to handle the fast nature of eye movements with the relative complexity of video transcoding and also take into account the delay associated with transmission in the network. Such a delay requires additional consideration in perceptual encoding because it increases the size of the area that requires high-quality coding. We present a hybrid scheme, one of the first to our knowledge, that combines eye tracking with fast in-line scene analysis to drastically narrow the high acuity area without the loss of eye-gaze containment.
