    Increasing the bandwidth or bit rate in real-time video applications to improve the quality of images is typically impossible or too expensive. Postprocessing appears to be the most feasible solution because it does not require any existing standards to be changed. Markedly reducing blocking effects can increase compression ratios for a particular image quality or improve the quality with respect ... View full abstract»

  • Motion-compensated residue preprocessing in video coding based on just-noticeable-distortion profile

    We present a motion-compensated residue signal preprocessing scheme in video coding scheme based on just-noticeable-distortion (JND) profile. Human eyes cannot sense any changes below the JND threshold around a pixel due to their underlying spatial/temporal masking properties. An appropriate (even imperfect) JND model can significantly help to improve the performance of video coding algorithms. Fr... View full abstract»

  • A real-time pattern selection algorithm for very low bit-rate video coding using relevance and similarity metrics

    Very low bit-rate video coding using regularly shaped patterns to represent moving regions in macroblocks has good potential for improved coding efficiency. This paper presents a real-time pattern selection (RTPS) algorithm, which uses a pattern relevance and similarity metric to achieve faster pattern selection from a large codebook. For each applicable macroblock, the relevance metric is applied... View full abstract»

  • Highly scalable, low-complexity image coding using zeroblocks of wavelet coefficients

    Publication Year: 2005, Page(s):762 - 770
    Cited by:  Papers (4)

    We propose a new highly scalable wavelet transform-based image coder, called S-SPECK, on the extension of a well-known zero-block image coder SPECK, by achieving not only distortion scalability, resolution scalability, and region of interest (ROI) retrievability, but also excellent compression performance with very low computational complexity. Though new features have been introduced into S-SPECK... View full abstract»

  • Motion estimation computational complexity reduction with CNN shape segmentation

    Publication Year: 2005, Page(s):771 - 777

    The MPEG-4 core profile enables object-based coding. A core profile encoder may also have to be able to carry out simple profile frame-based coding. Frame-based coding is, for instance, needed when the object-based functionalities are not used or the target decoder has only simple profile capabilities. cellular nonlinear networks (CNN) offer an effective method to implement the segmentation needed...

  • Spatial and temporal error concealment algorithms of shape information for MPEG-4 video

    Publication Year: 2005, Page(s):778 - 783
    Cited by:  Papers (7)

    In this paper, new methods for error concealment of shape information are proposed for compressed MPEG-4 bit-streams transmitted over error prone channels. For spatial domain, the proposed approach employs the Bezier curve fitting to approximate and outline the intra-video object plane (I-VOP). For temporal domain, the proposed scheme uses the weighted side matching criterion to reconstruct the in... View full abstract»

  • An effective variable block-size early termination algorithm for H.264 video coding

    The H.264 video coding standard provides considerably higher coding efficiency than previous standards do, whereas its complexity is significantly increased at the same time. In an H.264 encoder, the most time-consuming component is variable block-size motion estimation. To reduce the complexity of motion estimation, an early termination algorithm is proposed in this paper. It predicts the best mo... View full abstract»

  • Adaptive irregular pattern search with matching prejudgment for fast block-matching motion estimation

    Publication Year: 2005, Page(s):789 - 794

    In this paper, a simple and effective fast block matching algorithm (BMA) is proposed, called adaptive irregular pattern search with matching prejudgment (AIPS-MP). In the AIPS-MP, a dynamic search pattern, adaptive irregular pattern (AIP), is constructed for each block based on its spatial and temporal neighboring motion vectors (MVs). The AIP is used to quickly identify the best center point for... View full abstract»

    It is well known that low bit rate block-based discrete cosine transform coded image exhibits visually annoying coding artifacts. In this paper, we proposed a projection onto convex sets (PCOS)-based deblocking algorithm using a novel region smoothness constraint set for graphic images containing objects with smooth regions. The smoothness constraint set is obtained by an explicit modeling of smoo... View full abstract»

  • Real-time computation of Zernike moments

    Zernike moments have been proven to be very powerful image descriptors. However, their computational complexity makes them unsuitable for real-time applications. In this paper, a mathematical relationship between geometric and Zernike moments is extracted. In this way, the computation of geometric moments is adequate to derive Zernike moments. Since geometric moments can be efficiently implemented... View full abstract»
