Abstract

This paper presents a psychophysical study that measures the perceptual thresholds of a new factor called Color-plus-Depth Level-of-Detail peculiar to polygon-based 3D teleimmersive video. The results demonstrate the existence of Just Noticeable Degradation and Just Unacceptable Degradation thresholds on the factor. In light of the results, we describe the design and implementation of 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.
