“…In these experiments, the allocation remains stable across most of the range of bitrates, with between 13% and 23% of the total bitrate dedicated to the disparity map. This is consistent with the heuristic ratio of 10% proposed in [9]. The allocation is similar whether the baseline is small, like in Tsukuba, or reasonably large, like in Teddy.…”

Abstract-We propose a wavelet-based codec for the static Depth-Image-Based Representation (DIBR), which allows viewers to freely choose the viewpoint. The proposed codec jointly estimates and encodes the unknown depth map from multiple views using a novel Rate-Distortion (RD) optimization scheme. The rate constraint reduces the ambiguity of depth estimation by favoring piecewise-smooth depth maps. The optimization is efficiently solved by a novel dynamic programming along trees of integer wavelet coefficients. The codec encodes the image and the depth map jointly to decrease their redundancy and to provide a RD-optimized bitrate allocation between the two. The codec also offers scalability both in resolution and in quality. Experiments on real data show the effectiveness of the proposed codec.

“…Now part of the MPEG-4 standard [8,9], this representation allows arbitrary views to be rendered in the vicinity of these pairs. Since depth maps tend to have lower entropies than images, the DIBR leads to compact bitstreams.…”

“…3D video applications can be grouped into two categories: free-viewpoint video [1] and 3D TV [2]. In free-viewpoint video, the viewer can interactively choose his/her viewpoint in 3D space to observe a real-world scene from preferred perspectives [1].…”

“…3D TV refers to the extension of traditional 2D TV displays to displays capable of 3D rendering. Advanced autostereoscopic displays can support head-motion parallax, by decoding and displaying multiple views from different view-points simultaneously [2]. The content in above scenarios can be represented by multiple views, which of each is a traditional 2D sequence that was captured by a camera and can be used for 2D digital TV.…”

During the standardization of MVC, there was also a project namely Joint Multiview Video Model (JMVM), which focused on the advanced coding tools that are potentially useful. Those coding tools adopted into JMVM, including illumination compensation and motion skip, have not been added into MVC specification. In this paper, coding techniques in MVC as well as the tools in JMVM are described and discussed, focusing on the coding efficiency.

“…One of the main aims of emerging audio-visual (AV) applications is to remove the passiveness of viewing a captured event or scene [8]. Such systems encourage users to explore and navigate AV scenes by allowing them to specify their own viewpoint and orientation.…”
