Gaze-Contingent Computational Displays: Boosting perceptual fidelity
Michael Stengel, Marcus A. Magnor · IEEE Signal Processing Magazine · 2016
Contemporary digital displays feature multimillion pixels at ever-increasing refresh rates. Reality, on the other hand, provides us with a view of the world that is continuous in space and in time. The discrepancy between viewing the physical world and its sampled depiction on digital displays gives rise to perceptual quality degradation. By measuring or estimating where we look, a new breed of gaze-contingent algorithms aims to exploit the way we visually perceive digital images and videos to remedy visible artifacts. In this article, we provide an overview of recent developments in computational display algorithms that enhance perceived visual quality of conventional video footage when viewed on commodity monitors, projectors, or headmounted displays (HMDs).
