3D video coding is one of the most popular research area in multimedia. This paper reviews the recent progress of the coding technologies for multiview video (MVV) and free view-point video (FVV) which is represented by MVV and depth maps. We first discuss the traditional multiview video coding (MVC) framework with different prediction structures. The rate-distortion performance and the view sw...

High efficiency video coding (HEVC) [1] is a new video coding standard developed by Joint Collaborative Team on Video Coding (JCT-VC) of ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). Currently, most of coding techniques are established and HEVC version 1 will be released in January 2013 [2]. We ex‐ pect that HEVC is widely used in various applications ...

In multimedia system, there are several video coding standards such as MPEG-1/2/4 [1]-[3], H.264/AVC [4], VC-1 [5], they are the source coding technology basis for digital multimedia applications. Despite of the emerging HEVC standard [6], H.264/AVC is the most mature video coding standard [4] [9]. China Audio and Video Coding Standard (AVS) is a new standard targeted for video and audio coding...

In the chain of stereoscopic video processing, stereoscopic video coding and viewing are usually two independent stages. Conventional stereoscopic video coding puts emphasis on improving the coding efficiency by seeking the optimal trade-off between the coding bit-rate and the signal-based distortion, while neglecting the perceptual behaviors of binocular combination when stereoscopic video is ...

Video coding standards are essential to a wide range of applications, but have certain limitations. New, flexible approaches to video compression have the potential to speed up adoption of new coding techniques, to improve compression performance through adaptive coding and to support multiple coding standards on a single platform. In this paper we describe the MPEG Reconfigurable Video Coding ...

3D wavelet video coding provides an elegant fulldimensional solution for scalable video coding. However, due to the Motion-Compensated Temporal Filtering (MCTF) with open-loop structure and no good rate distortion optimization trade-off between the texture coding and overhead coding of the corresponding mode and motion vectors within narrow bandwidth, its performance is unsatisfactory at low bi...

Adaptive video coding algorithms are digital video compression algorithms that can adapt the encoding of a video stream dynamically based on the amount of bandwidth available on the network. While such algorithms are more complicated than traditional video coding algorithms, they are attractive because of their inherent robustness to changes in network load (i.e., network congestion). Adaptive ...

• Fundamentals of Wavelet-Based Scalable Video Coding : The purpose and the general concept of scalable video coding will be introduced in this section. We also give a brief comparison between the major two scalable video coding methods, which are the wavelet-based scalable video coding and H.264/SVC. In addition, we introduce the structure of wavelet-based scalable video coding in this section...
