Adaptive Multiview Video Coding Scheme Based on Spatiotemporal Correlation Analyses

چکیده
© 2009 Yun Zhang et al. 151 In this paper, we propose an adaptive multiview video coding scheme based on spatiotemporal correlation analyses using hierarchical B picture (AMVC-HBP) for the integrative encoding performances, including high compression efficiency, low complexity, fast random access, and view scalability, by integrating multiple prediction structures. We also propose an in-coding mode-switching algorithm that enables AMVC-HBP to adaptively select a better prediction structure in the encoding process without any additional complexity. Experimental results show that AMVC-HBP outperforms the previous multiview video coding scheme based on H.264/MPEG-4 AVC using the hierarchical B picture (MVC-HBP) on low complexity for 21.5%, on fast random access for about 20%, and on view scalability for 11% to 15% on average. In addition, distinct coding gain can be achieved by AMVC-HBP for dense and fast-moving sequences compared with MVCHBP.

متن کاملFocus Mismatches in Multiview Systems and Efficient Adaptive Reference Filtering for Multiview Video Coding
In this paper, we analyze focus mismatches among cameras utilized in a multiview system, and propose techniques to efficiently apply our previously proposed adaptive reference filtering (ARF) scheme to inter-view prediction in multiview video coding (MVC). We show that, with heterogeneous focus setting, the differences exhibit in images captured by different cameras can be represented in terms ...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
متن کاملMultiview Video Coding Based on Global Motion Model
In this paper, we present a novel scheme for coding multiview video sequence based on global motion prediction between adjacent views. For that, the left-most view is compressed as reference sequence using standard block-based motion compensated prediction coding. And its right view is compressed with global motion prediction from the left view images. In the prediction, an eight-parameter glob...
