    The bimodal acoustic-visual effect is of extreme importance in human face-to-face communication; it has been broadly investigated and the improvement in understanding when visual cues are integrated with speech has been clearly demonstrated, with particular emphasis in noisy environments. In this paper, we propose a novel synchronization procedure for speech and text, consisting of a neural networ... View full abstract»

    We present a generic architecture for content based retrieval of images, which can be extended to the requirements of large distributed and heterogeneous collections. The system is modeled as a multi agent system where an autonomous search agent encapsulates independent image retrieval algorithms. An optimal team of agents is dynamically selected for every retrieval problem. A flexible protocol al... View full abstract»

  • A pruning based fast rate control algorithm for MPEG coding

    Publication Year: 1999, Page(s):403 - 407
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (64 KB)

    Presents a fast rate control scheme that regulates the coded bit stream generated by an MPEG video encoder such that the resulting variable-rate compressed bit stream can be transmitted over a fixed-rate channel. A new bit-rate regulation scheme is proposed using a technique called pruning, in which only the required number of low-frequency coefficients of the discrete cosine transform (DCT) are c...

    According to the basic optimization principle of artificial neural networks, a novel kind of neural network model for solving the quadratic programming problem is presented. The methodology is based on the Lagrange multiplier theory in optimization and seeks to provide solutions satisfying the necessary conditions of optimality. The equilibrium point of the network satisfies the Kuhn-Tucker condit... View full abstract»

    Neural networks, due to their excellent capabilities for modelling process behaviour, are gaining precedence over traditional empirical modelling techniques, such as statistical methods. While neural networks have good ability to map any reasonable continuous function, they do not easily explain how the inputs are related to an output, and also whether the selected inputs have any significant rela...

    Fractals are famous for their beauty and fractal techniques are employed for smaller storage space requirements when storing images. Fractal geometry has gradually established its importance in the study of image characteristics. The concept of multiple reduction copy machine (MRCM) has been used for creating fractals for a long time. A modified MRCM has been designed to generate fractal patterns.... View full abstract»

    The management of long lived transactions is an interesting topic in the application of databases for long term enterprise requests. Some methods have been proposed to manage this type of transaction well: nested transaction model, SAGAS model, etc. However, the models are not always successful at controlling various classes of long lived transactions effectively. We describe our 3-layer model of ... View full abstract»

  • Using Kohonen map for the placement of regular VLSI designs

    Publication Year: 1999, Page(s):65 - 69
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (32 KB)

    The paper presents the formulation of a VLSI placement problem for regular designs (gate arrays) using a Kohonen self-organizing map. An abstract specification of the design is converted to a set of appropriate input vectors using a mathematical method, called “multidimensional scaling”. These vectors which have, in general, higher dimensionality, are fed to the self-organizing map at ... View full abstract»

    The issue of handling imperfect information in a multimedia database system is addressed. The issue of filtering imperfect information appears to be especially crucial in the context of a multimedia system since multimedia data are very often uncertain and/or imprecise. This work is mainly situated in the framework of the possibility theory-based approach which proves to be best suited to qualitat... View full abstract»

    Since conflict negotiation requires many humans interacting, the modeling of human decision-making within conflict negotiation requires accuracy at both the individual cognitive behavior level and the group interaction level. The key to this accuracy is the characterization of the attributes of conflict negotiation strategies and of individual human decision-making processes. The characteristics o... View full abstract»

    One of the most prevalent problems in modern telecommunication networks is the efficient routing of multicast connections. The formal formulation of this problem reduces to a graph-theoretical problem known as the Steiner tree problem, that is proved to be NP-complete. We present an efficient solution for the Steiner tree problem with application to multicast routing, based on a hybridized genetic... View full abstract»
