Abstract

This paper presents a psychophysical approach to control a new factor called Color-plus-Depth Level-of-Detail in polygon-based 3D tele-immersive video. Based on our psychophysical study that demonstrates the existence of perceptual thresholds on the factor, we present a real-time perception-based quality adaptor for 3D tele-immersive video. Our experimental results show that the adaptation scheme can reduce resource usage while considerably enhancing the overall perceived visual quality.
