    We describe some improvements to a proposed algorithm which encodes the error due to motion compensation in a videoconferencing codec. The algorithm involves lattice quantization using the 8-dimensional E8 lattice. We show that by using a different but equivalent form of E8 based on the extended Hamming code, we can significantly reduce storage requirements and computational complexity at the rece...

    We have shown in previous works that overcomplete signal decomposition using matching pursuits is an efficient technique for coding motion-residual images in a hybrid video coder. Others have shown that alternate basis sets may improve the coding efficiency or reduce the encoder complexity. In this work, we introduce for the first time a design methodology which incorporates both coding efficiency... View full abstract»

    Video query by semantic keywords is one of the most challenging research issues in video data management. To go beyond low-level similarity and access video data content by semantics, we need to bridge the gap between the low-level representation and high-level semantics. This is a difficult multimedia understanding problem. We formulate this problem as a probabilistic pattern-recognition problem ... View full abstract»

  • Wavelet-based optical flow estimation

    Publication Year: 2002, Page(s):1 - 12

    A new algorithm for accurate optical flow (OF) estimation using discrete wavelet approximation is proposed. The computation of OF depends on minimizing the image and smoothness constraints. The proposed method takes advantages of the nature of wavelet theory, which can efficiently and accurately approximate any function. OF vectors and image functions are represented by means of linear combination... View full abstract»

    This work explores the data reuse properties of full-search block-matching (FSBM) for motion estimation (ME) and associated architecture designs, as well as memory bandwidth requirements. Memory bandwidth in high-quality video is a major bottleneck to designing an implementable architecture because of large frame size and search range. First, the memory bandwidth in ME is analyzed and the problem ... View full abstract»

    For pt. I see ibid., vol.12 , no.1, (2000).We introduce two models for predicting the rate and distortion of the matching-pursuit video codec. The first model is based on a pre-coding analysis pass using the full matching-pursuit dictionary. The second model is based on a reduced-complexity analysis pass. We evaluate these models for use within existing rate-distortion optimization techniques. Our... View full abstract»
