Virtual reality (VR) provides unprecedented immersive experience using high-resolution spherical stereoscopic panoramic video. Such an experience is achieved by using head-mounted display (HMD) which has very strict latency bounds in order to respond promptly to user movements. Conventional streaming of VR video requires large bandwidth because the entire captured panorama is transmitted. However,...
The bandwidth and storage restrictions of consumer devices and conventional delivery infrastructures on stereoscopic 3D video require efficient compression methods to save the bandwidth and preserve the perceptive quality at the same time. Compression efficiency is actually determined as the visual quality achieved for a certain amount of bitrate. In this paper, a perception aware coding scheme is...
Recent developments of three-dimensional (3D) video coding greatly rely on the use of Multiview Video plus Depth (MVD) data format for representing a 3D scene. This type of data can be coded with conventional video compression schemes and can enable advanced 3D video functionality, such as rendering of virtual views at the decoder side. The MVD represents a 3D scene from different viewing angles as...
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...
A Fourier-domain representation of an image exhibits a property where a translation of the image is included in the phase term. This property extends to the Discrete Cosine Transform, where the translation is encoded in the signs of the coefficients. An interpretation of this property for use as a similarity measure in local stereo matching is explored with an efficient way of comparing the transformed...
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...
