Asymmetric stereoscopic video coding, where one view has a higher quality than the other, has been researched widely. In order to balance the quality difference between views, it has been suggested to alternate the higher-quality view periodically. However, it has also been found out that inter-view prediction is more effective when the source of prediction is the higher-quality view. In this paper,...
Conventional mixed-resolution (MR) stereoscopic video where one view has full resolution (FR) and the other view has a lower resolution has shown to provide similar subjective quality compared to symmetric FR stereoscopic video while decreasing the encoding complexity considerably. In this paper, we propose a new cross-asymmetric mixed-resolution scheme where both views have a lower resolution compared...
Under many viewing circumstances, asymmetric stereoscopic video coding provides similar perceived quality with significant decrease in bitrate, computational complexity, and memory usage compared to conventional stereoscopic video coding. However, in other circumstances, users may prefer conventional symmetric stereoscopic video to asymmetric stereoscopic video. This paper presents a stereoscopic...
In mixed-resolution (MR) stereoscopic video, one view is presented with a lower resolution compared with the other one; therefore, a lower bitrate, a reduced computational complexity, and a decrease in memory access bandwidth can be expected in coding. The human visual system is known to fuse left and right views in such a way that the perceptual visual quality is closer to that of the higher-resolution...
A novel asymmetric stereoscopic video coding method is presented in this paper. The proposed coding method is based on uneven sample domain quantization for different views and is typically applied together with a reduction of spatial resolution for one of the views. Any transform-based video compression, such as the Advanced Video Coding (H.264/AVC) standard, can be used with the proposed method...
Asymmetric stereoscopic video coding takes advantage of the binocular suppression of the human vision by representing one of the views with a lower quality. This paper describes a subjective quality test with asymmetric stereoscopic video. Different options for achieving compressed mixed-quality and mixed-resolution asymmetric stereo video were studied and compared to symmetric stereo video. The bitstreams...
In mixed-resolution (MR) stereoscopic video, one of the views has a lower resolution compared to the other one, hence providing means for improved compression. The underlying assumption in MR stereoscopic video is that the human visual system fuses the left and right views in such a way that the perceived image quality is close to that of the higher-resolution view. This paper describes a subjective...
