    Loopy belief propagation (BP) is an effective solution for assigning labels to the nodes of a graphical model such as the Markov random field (MRF), but it requires high memory, bandwidth, and computational costs. Furthermore, the iterative, pixel-wise, and sequential operations of BP make it difficult to parallelize the computation. In this paper, we propose two techniques to address these issues...

    An efficient lossless video codec based on H.264/AVC that uses the Hadamard transform and adaptive truncation (HTAT) method is proposed. Most lossless video coding algorithms avoid transforms in their coding procedures. However, without this transformation, those lossless video coding algorithms cannot take advantage of data compaction. The HTAT method adopts the Hadamard transform to compact data...

    This paper aims to optimize the overall video quality and traffic performance for multi-rate video multicast over hybrid wired/wireless networks. In order to perform layered utility maximization over tiered networks, we propose a joint source-network flow optimization scheme where individual layers of the scalable video stream are imposed on their optimal multicast paths and associated rates for t...

    This paper presents a novel method for the protection of bitstreams of state-of-the-art video codec H.264/AVC. The problem of selective encryption (SE) is addressed along with the compression in the entropy coding modules. H.264/AVC supports two types of entropy coding modules. Context-adaptive variable length coding (CAVLC) is supported in H.264/AVC baseline profile and context-adaptive binary ar... View full abstract»

    High-spatial-resolution videos offer the possibility of viewing an arbitrary region-of-interest (RoI) interactively. Zoom functionality enables watching high-resolution content even on displays of lower spatial resolution. If arbitrary regions corresponding to arbitrary zoom factors can be served to the user, the transmission and/or decoding of the entire high-spatial-resolution video can be avoid...

  • Multiple Description Coding for H.264/AVC With Redundancy Allocation at Macro Block Level

    Publication Year: 2011 , Page(s): 589 - 600

    In this paper, a novel multiple description video coding scheme is proposed to insert and control the redundancy at macro block (MB) level. By analyzing the error propagation paths, the relative importance of each MB is determined. The paths, in practice, depend on both the video content and the adopted video coder. Considering the relative importance of the MB and the network status, an unequal p... View full abstract»

    Fidelity range extensions of H.264/AVC adopt variable block size (VBS) transform techniques to employ 8 × 8/4 × 4 Hadamard transforms adaptively during the fractional motion estimation. In this literature, the hardwired VBS Hadamard transform accelerator is developed with the following contributions: 1) developed a hardware reusing scheme between 8 × 8 and 4 × 4 transfo...

    Faced with the growing population of seniors, developed countries need to establish new healthcare systems to ensure the safety of elderly people at home. Computer vision provides a promising solution to analyze personal behavior and detect certain unusual events such as falls. In this paper, a new method is proposed to detect falls by analyzing human shape deformation during a video sequence. A s... View full abstract»

    Visual saliency plays an important role in various video applications such as video retargeting and intelligent video advertising. However, existing visual saliency estimation approaches often construct a unified model for all scenes, thus leading to poor performance for the scenes with diversified contents. To solve this problem, we propose a multi-task rank learning approach which can be used to... View full abstract»

    This paper presents a highly efficient audio-visual recognition system in compression domain. For face recognition systems, the multiband feature fusion method selects the wavelet subbands that are invariant to illumination and facial expression variations. These subbands will be extracted directly from the inverse quantization in the compression system. By taking the inverse quantized wavelet coe... View full abstract»

    The addition of a new component to the traditional synthesis-based texture video coding algorithm is investigated in this paper. That is, we add the side information in the form of low-quality video to enhance the texture video synthesis performance with reducing the unpleasant mismatch between analyzed and synthesized regions. As compared with the conventional synthesis algorithm, our algorithm i... View full abstract»

    This paper jointly considers the mechanisms of rate control and the rate-distortion optimization (RDO) for the H.264/AVC hardware encoder. The proposed architecture performs intra prediction and inter prediction with our rate control mechanism in the first two stages. In addition, a low complexity macroblock (MB)-level mean absolute difference (MAD) prediction algorithm which considers both the mo... View full abstract»

    The use of context knowledge is critical for understanding human actions, which typically occur under particular scene settings with certain object interactions. For instance, driving car usually happens outdoors, and kissing involves two people moving toward each other. In this paper, we investigate the problem of context modeling for human action retrieval. We first identify ten simple object-le... View full abstract»

    The quality of video is ultimately judged by human eye; however, mean squared error and the like that have been used as quality metrics are poorly correlated with human perception. Although the characteristics of human visual system have been incorporated into perceptual-based rate control, most existing schemes do not take rate-distortion optimization into consideration. In this paper, we use the... View full abstract»
