    A new rate control scheme for H.264 video encoding with enhanced rate and distortion models is proposed in this work. Compared with existing H.264 rate control schemes, our scheme has offered several new features. First, the inter-dependency between rate-distortion optimization (RDO) and rate control in H.264 is resolved via quantization parameter estimation and update. Second, since the bits of t...

    The rate-distortion (R-D) optimization technique plays an important role in optimizing video encoders. Modeling the rate and distortion functions accurately in acceptable complexity helps to make the optimization more practical. In this paper, we propose a bit-rate estimation function and a distortion measure by modeling the transform coefficients with spatial-domain variance. Furthermore, with qu... View full abstract»

  • Rate-Distortion-Authentication Optimized Streaming of Authenticated Video

    We define authenticated video as decoded video that results from those received packets whose authenticities have been verified. Generic data stream authentication methods usually impose overhead and dependency among packets for verification. Therefore, the conventional rate-distortion (R-D) optimized video streaming techniques produce highly sub-optimal R-D performance for authenticated video, si... View full abstract»

    A novel hybrid error-resilience and error-concealment technique for embedded wavelet coders is presented. Aimed to resolve data loss in real-time visual transmission over the packet erasure channels, the proposed method incorporates data partitioning and multiple description coding into the set partitioning in hierarchical tree (SPIHT's) encoding process. Each of the spatial-orientation trees of S... View full abstract»

  • Fast Algorithm and Architecture Design of Low-Power Integer Motion Estimation for H.264/AVC

    In an H.264/AVC video encoder, integer motion estimation (IME) requires 74.29% computational complexity and 77.49% memory access and becomes the most critical component for low-power applications. According to our analysis, an optimal low-power IME engine should be a parallel hardware architecture supporting fast algorithms and efficient data reuse (DR). In this paper, a hardware-oriented fast alg... View full abstract»

    This paper presents a fast algorithm and its VLSI architecture for H.264 fractional motion estimation. Motivated by the high correlation of cost between neighboring fractional pel position, the proposed algorithm efficiently explores the neighborhood position around the minimum one and thus skips other unlikely ones. Thus, the proposed search pattern and early termination under constant quantizati... View full abstract»

    Feature selection and extraction is a key operation in video analysis for achieving a higher level of abstraction. In this paper, we introduce a general framework to extract a new spatio-temporal feature that represents the directions in which a video is regular, i.e., the pixel appearances change the least. We propose to model the directions of regular variations with a 3-D vector field, which is... View full abstract»

    A system for visual information analysis and classification based on a biologically inspired visual selective attention model with knowledge structuring is presented. The system is derived from well-known analogous processes in the visual system of primates and inference procedures of the human brain. It consists of three main units: biologically inspired visual selective attention, knowledge stru... View full abstract»

    This paper deals with the views synthesis problem and proposes an automatic method for specifying the virtual camera position and orientation in an uncalibrated setting, based on the interpolation and extrapolation of the motion among the reference views. Novel images can be rendered from virtual cameras moving on parametric trajectories. Synthetic and real experiments illustrate the approach View full abstract»

    In this paper, a generalized statistical tool is introduced to estimate key frames in a video sequence. The tool works based on the inter-relationship between different features of image frames in a video. The image feature vectors are plotted in feature space as points and a randomness measure is determined from the distribution of these points. The randomness measure of the feature vectors is de...

  • A Computationally Efficient Super-Resolution Algorithm for Video Processing Using Partition Filters

    We propose a computationally efficient super-resolution (SR) algorithm to produce high-resolution video from low-resolution (LR) video using partition-based weighted sum (PWS) filters. First, subpixel motion parameters are estimated from the LR video frames. These are used to position the observed LR pixels into a high-resolution (HR) grid. Finally, PWS filters are employed to simultaneously perfo... View full abstract»

    For efficient image retrieval, most existing methods that adopt a tree-structured hierarchy exploit a subtree pruning scheme, based on the triangle inequality of a distance metric, during the tree traversal. In this paper, we propose a refined pruning scheme for the tree-structured hierarchy by introducing a novel notion of the node distance to subcluster (NDS) and validate it in both theoretical ...

    This paper extends the lifting-based motion threading (MTh) technique from the frame-based coding to the object-based coding, attracted by the unique advantages of the object-based coding that do not exist in other coding schemes. The boundary effects, which exist in spatial and temporal wavelet transforms due to the manner of object-based coding, are well suppressed by 3-D shape-adaptive discrete... View full abstract»
