    Utilizing video correlations among views would definitely improve multiview video compression in terms of coding efficiency, which usually requests an expensive system to collect videos from different cameras and jointly compress them. Thanks to recent developments on distributed video coding, this paper proposes a new multiview video coding scheme based on Wyner-Ziv (WZ) coding technique, in whic... View full abstract»

    Most consumer digital cameras use a single light sensor which captures color information using a color filter array (CFA). This produces a mosaic image, where each pixel location contains a sample of only one of three colors, either red, green or blue. The two missing colors at each pixel location must be interpolated from the surrounding samples in a process called demosaicking. The conventional ... View full abstract»

    In this paper, we propose a fast full-pel variable block size motion estimation algorithm called fast Walsh search in variable block size (FWS-VBS). FWS-VBS employs a new error measurement defined in Walsh-Hadamard domain, which is called partial sum-of-absolute difference, to identify likely mismatches. Mismatches are rejected by thresholding method and the thresholds are determined adaptively to... View full abstract»

    Since variable block-size motion compensation (MC) and rate-distortion optimization (RDO) techniques are adopted in H.264/MPEG-4 AVC, modes and motion vectors (MVs) in input stream can no longer be reused equivalently efficient over a wide range of bit rate in transcoded streams. This paper proposes a new RDO model to maintain good coding efficiency and greatly reduce computation of the H.264/MPEG... View full abstract»

    Edge is an important feature in video classification which finds applications in video representation and coding. In H.264/AVC, intra-prediction mode decision (a computationally intensive process) is based on the orientation of the edges in the macroblock. In this paper, we first investigate the difference properties derived from three coefficients in the non-normalized Haar transform (NHT) domain... View full abstract»

    Look-up table (LUT)-based data hiding is a simple and efficient technique to hide secondary information (watermark) into multimedia work for various applications such as copyright protection, transaction tracking or content annotation. This paper studies the distortion introduced by a general LUT-based data hiding. We find that designing LUT according to the distribution of host data and watermark... View full abstract»

    Watermark resistance to geometric attacks is an important issue in the image watermarking community. Most countermeasures proposed in the literature usually focus on the problem of global affine transforms such as rotation, scaling and translation (RST), but few are resistant to challenging cropping and random bending attacks (RBAs). The main reason is that in the existing watermarking algorithms,... View full abstract»

    We explore predictive coding for the JPEG baseline sequential algorithm in this article. Our objective is to reduce inter-block redundancy of discrete cosine transform (DCT) blocks. We first present an implementation of image interpolation approach and develop a method for predicting AC coefficients of a block in terms of sum of pixels (or dc coefficients) of some surrounding patches. If we use 2-... View full abstract»

  • Nonlinear flicker compensation for archived film sequences using motion-compensated graylevel tracing

    We present a novel approach for the compensation of temporal brightness variations (commonly referred to as flicker) in archived film sequences. The proposed method is motivated by fundamental principles of photographic image registration and provides a substantial level of adaptation to temporal but also spatial variations of picture brightness. Additionally, our scheme provides an efficient mech... View full abstract»

  • Nonreference Method for Estimating PSNR of MPEG-2 Coded Video by Using DCT Coefficients and Picture Energy

    Irreversible video coding like MPEG-2 may cause deterioration in picture quality depending on the properties of the source images and coding type. A monitoring technology to assess picture quality with fluctuations is needed for digital video services. We previously proposed a method to estimate the peak signal-to-noise-ratio (PSNR) of MPEG-2 coded video by using bit stream information. The method... View full abstract»

  • A Subfield Coding Algorithm for the Reduction of Gray Level Errors Due to Line Load in a Plasma Display Panel

    Displayed gray level of a plasma display panel (PDP) is often different from the intended target gray level due to the variation of the line load (the number of on-cells on a scan line). The conventional gray level generation algorithm does not take this difference into consideration and may deteriorate the displayed image quality. In this paper, luminance ratio variations that depend on the line ... View full abstract»

  • Optimal Bit Allocation for Joint Texture-Aware Contour-Based Shape Coding and Shape-Adaptive Texture Coding

    In this paper, an operationally optimal joint shape and texture coding algorithm is proposed that uses shape-adaptive texture coding as well as texture-aware shape coding. The solution is optimal in the operational rate distortion sense, i.e, given the coding setup, the solution will guarantee the smallest possible distortion for a given rate. The shape is approximated using polygons or higher ord... View full abstract»

    Shape masks are used in object-based video coding, such as MPEG-4 part 2, to specify the boundaries of a video object. The term ldquobinary shaperdquo is used to describe shape masks where each pixel is either completely inside the object or completely outside it, i.e., there is no blending of pixels at object boundaries. In this paper, we present a new lossless block-based coding algorithm for bi... View full abstract»

    As adoption of the newly standardized H.264 becomes increasingly more widespread, efforts must be made to transcode video from earlier standards, such as MPEG-2, to the H.264 format. One aspect of transcoding is the conversion from the discrete cosine transform (DCT) used in MPEG-2 to the integer-based DCT of H.264, the integer cosine transform. By investigating the structure of the transform kern... View full abstract»
