    Recent video coding standards such as H.264 offer the flexibility to select reference frames during motion estimation for predicted frames. In this paper, we study the optimization problem of jointly selecting the best set of reference frames and their associated transport QoS levels in a multipath streaming setting. The application of traditional Lagrangian techniques to this optimization problem... View full abstract»

    Automatic detection of wipes and their frame ranges is important for the purpose of reliable video parsing and video database indexing. Wipes are difficult to detect because of the complexity and variety of the transition effects. Many of the existing wipe detection algorithms could detect only a few wipe effects. The false/miss detection problem caused by motion is also very serious. In this pape... View full abstract»

    In this work, we consider a CDMA cell with multiple terminals transmitting video signals. We adapt the system parameters to minimize the sum of compression powers and transmitter powers of all users while guaranteeing the received video quality at each terminal. The adjustable parameters at user i include the transmitter power Pt,i, the video coding bit rate Rs,i, and video e... View full abstract»

    Planar mirror has been used successfully in the catadioptric stereo systems to capture image pairs with only a single camera. These planar catadioptric stereo (PCS) systems not only provide radiometric advantages over traditional two camera stereo, but also reduce the complexity and cost of acquiring stereoscopic video. One problem with these PCS sensors is that image pairs taken by them are usual... View full abstract»

    Compared with the video programs taken by professionals, home videos are always with low quality content resulted from non-professional capture skills. In this paper, we present a novel spatiotemporal quality assessment scheme in terms of low-level content features for home videos. In contrast to existing frame-level-based quality assessment approaches, a type of temporal segment of video, subshot... View full abstract»

    Conventional block-based video coding with subpixel motion compensation, requires a large pool of memory for storing up-sampled reference frames. The size of this memory for many applications, especially for encoding high definition source materials is a major design consideration. In this paper, the concept of reciprocal block matching is introduced based on the relativity of motion, especially, ... View full abstract»

    Content adaptation is an important issue of multimedia frameworks in order to achieve universal multimedia access (UMA), i.e., to enable consumption of multimedia content independently of the given resource limitations, terminal capabilities, and user preferences. The digital item adaptation (DIA) standard, one of the core specifications of the MPEG-21 framework, supports content adaptation consid... View full abstract»

    In general, a large amount of memory accesses are required for context-based adaptive variable-length coding decoding in H.264/AVC standard. It is a serious problem for applications such as videophone and digital multimedia broadcasting services because of the considerable power consumption of the memory access function. In order to reduce the memory access, we carefully examined the codewords in ... View full abstract»

    Effectively coding multiview visual content is an indispensable research topic because multiview image and video that provide greatly enhanced viewing experiences often contain huge amounts of data. Generally, conventional hybrid predictive-coding methodologies are adopted to address the compression by exploiting the temporal and interviewpoint redundancy existing in a multiview image or video seq...

    Current systems often assume "worst case" resource utilization for the design and implementation of compression techniques and standards, thereby neglecting the fact that multimedia coding algorithms require time-varying resources, which differ significantly from the "worst case" requirements. To enable adaptive resource management for multimedia systems, resource-estimation mechanisms are needed.... View full abstract»

    In H.264/AVC, the rate-distortion optimization for mode decision plays a significant role to achieve its outstanding performance in terms of both compression efficiency and video quality. However, this mode decision process also introduces extremely high complexity in the encoding process especially the computation of the sum of squared differences (SSD) between the original and reconstructed imag...

    A scheme is proposed to implement commutative video encryption and watermarking during advanced video coding process. In H.264/AVC compression, the intra-prediction mode, motion vector difference and discrete cosine transform (DCT) coefficients' signs are encrypted, while DCT coefficients' amplitudes are watermarked adaptively. To avoid that the watermarking operation affects the decryption operat... View full abstract»

    It has been widely believed that motion-compensated update steps performed in the motion-compensated temporal filtering (MCTF) framework improve coding efficiency in comparison to conventional hybrid coding. However, the coding efficiency of MCTF update steps for scalable video coding has not been examined sufficiently in the past. In this paper, we investigate the efficiency of the decoder side u...

    Disparity estimation belongs to the most important, but difficult, problems in image processing and computer vision. Its importance stems from a wide range of applications, while its difficulty is related to ill-posedness. To date, numerous disparity estimation algorithms have been developed. In this paper, we consider a particular case of disparity estimation based on two views and a known alpha ... View full abstract»

    In the scalable video coder MC-EZBC, the motion-vector (MV) bitstream was not scalable in bitrate or resolution. In this short paper, we enhance MC-EZBC with a new scalable MV coder based on context adaptive binary arithmetic coding. Alphabet general partition of MV symbols is proposed to achieve accuracy or quality scalability of MVs. A selective layered structure is used to reduce the number of ... View full abstract»
