ABSTRACT3D processing techniques are really promising. However, several hurdles have to be overcome. In this paper, two of them are examined. The first is related to the high disparity management. It is currently not well mastered and its impact is strong for viewing 3D scene on stereoscopic screens. The second concerns the salient regions of the scene. These areas are commonly called Region-Of-Interest (RoI) in the image processing domain. The problem appears when there are more than one region-of-interest in a video scene. Indeed, it is then complicated for the eyes to scan them and especially if the depth difference between them is high. In this contribution, the 3D experience is improved by applying some effects related to RoIs. The shift between the two views is adaptively adjusted in order to have a null disparity on a given area in the scene. In the proposed approach, these areas are the visually interesting areas. A constant disparity on the salient areas improves the viewing experience over the video sequence.
This paper addresses the issue of video compression within professional studio environments. In particular, the study concerns the degradation of the video quality in the case of successive encoding/decoding operations in the presence of pixel shifting to reflect some processing that may occur during the production workflow.
An inter-view coding scheme is proposed for stereoscopic video applications such as 3D Digital Cinema. It tackles inter-view redundancy with efficient inter-view disparity-compensated filtering. In the temporal dimension, intra-coding with JPEG2000 is used to meet Digital Cinema specific requirements in terms of latency and random access. Inter-view disparity, as well as uncovered areas, are efficiently addressed within the inter-view Haar transform, and the resulting overhead information only amounts to a few percents of the bitstream. The proposed stereoscopic coding scheme delivers both left and right views with a high level of quality and yields to significant improvement in terms of bitrate saving and image quality in comparison with simulcast.
