“…Depth-image-based rendering (DIBR) can solve this problem because depth information can be compressed efficiently. The ATTEST project, which started in March 2002 as part of the European Information Society Technologies (IST), has proposed DIBR techniques because depth information as the additional data can be compressed efficiently below 64 Kbps [1,2,3].…”

This letter proposes a reliable depth-image-based rendering (DIBR) technique, which can provide users with reliable 3D services even if contents contain unknown or inappropriate values in some parameters. For the reliable DIBR, this letter presents how to set rendering parameters such as far/near clipping plane, convergence distance, and scale factor by taking mobile display size into consideration. Various experiments show that the proposed method can be effectively employed for 3D services based on DIBR over terrestrialdigital multimedia broadcasting (T-DMB).

3DTV provides realistic 3D effects to viewers by employing stereoscopic contents compared with 2D videos. This technology can be used in various applications, including games, education, films, etc. Hence, 3DTV is expected to have the dominant market of the next generation digital TV. However, the promotion of 3DTV is constrained by the lack of stereoscopic contents. There are several approaches for generating stereoscopic contents. It is a common way that the 3D videos are captured by stereoscopic cameras which is a type of camera with two or more lens. Stereoscopic contents are also generated from monocular 2D videos. It is well-known that there is no direct depth information in the conventional 2D contents. The aim of this work is to convert 2D videos into 3D videos. The 2D to 3D conversion technology can enrich stereoscopic contents, and promote the de-, Biao Hou 1 , and Licheng J iao 1 Abstr act. 2D to 3D conversion is an important task in 3DTV due to the lack of 3D contents. In this paper, we propose a novel framework of the 2D to 3D video conversion. The proposed framework consists of two main stages: depth map generation and virtual view synthesis. In the depth map generation, motion and relative-height cues are effectively used to generate depth maps. In the virtual view synthesis, depth-image-based-rendering (DIBR) is adopted to generate the left and right virtual views from the depth maps. Experimental results demonstrate that the proposed 2D to 3D conversion is very effective in generating depth maps and providing realistic 3D effects.

“…Because of the diversity of the real world, there exist various scene representations to build 3D video, such as model-based representation [4] and point sample based representation [5]. Among these representations, it is widely accepted that the representation of multiview color video plus its associated depth can provide both good rendering quality and flexible processing capability [6], [7]. Moreover, depth map or disparity map can efficiently describe the actual 3D information [8]- [10], while providing the backward compatibility with the existent 2D video.…”

Abstract-This paper presents a novel rate control technique for multiview video plus depth (MVD) based 3D video coding. In the proposed rate control technique, an image-stitching method is first utilized to simultaneously encode video and depth, and then a joint rate control algorithm for MVD is presented. The joint rate control algorithm is performed on three levels, namely view level, video/ depth level and frame level. In the view level, different proportions of rates are allocated for different types of views according to the pre-statistical rate allocation. In the video/depth level, the target rates for video and depth are discriminatorily assigned to guarantee the high quality of video for the backward-compatible display. In the frame level, the hierarchical rate allocation is used to regulate the target bits for each frame. In addition to the above mentioned rate control strategies, according to the special characteristics of multiview hypothetical reference decoder (HRD), the buffer-related rate control is also considered to prevent the decoder buffer from overflow or underflow even outputting multiple views. Experimental results show that the proposed rate control technique can accurately control the bit-rate to satisfy the requirements of 3D video systems.Index Terms-Multiview video coding, rate control, video plus depth representation, 3D video coding.
