This paper presents an experimental study on sub- jective thresholds in 3D stereoscopic video using different types of asymmetric coding. The research is focused on uniform and non-uniform asymmetric coding in the spatial quality domain. A new method providing an additional level of quality asymmetry in the spatial dimension of stereoscopic video is exploited based on 3D image regions with different perceptual relevance. Following an overview of related work on asymmetric coding, the paper describes an experimental study based on subjective testing using classic and non-uniform asymmetric coding of both still images and motion video. The results show that non-uniform asymmetric coding can be used to extend known quality thresholds at which the observers start to notice impairments in 3D video.
