    On the Generation of Codebooks for Vector Quantization,
    In this paper we investigate the problem of codebook generation for Vector Quantizers which optimize non-Euclidean as well as Euclidean distortions. A new algorithm for minimizing non-Euclidean distortions is introduced together with some speed-up heuristics. The structure of local minima for different distortion measures is analyzed statistically and using techniques for multidimensional scaling. The latter are also used to improve compression rates by codebook ordering,

    Retrieval by Image Content for Video and Image Databases: A Survey,
    Large databases of images and video data are now available. The management and exploitation of these new media databases require extensions of the traditional query mechanisms developed for accessing textual information. This survey reviews some recent works on the management of video and image data,

    VCB: A Video Clip Browser and More,
    Browsing is an interactive process through which the user decide when and where to focus the attention within a large database, by example in order to retrieve information in a video stream. This paper presents the 'Video Clip Browser', a set of tools designed to easily navigate into video clips, as well as some utilities for the automatic search of particular frames of the video stream. A peculiarity of this system is that the browsing tools can be used in an interleaved way giving high flexibility to the navigation process,

    A Review on Iconic Indexing for Large Visual Databases,
    The amount of information stored in form of images, pictures or videos is undergoing a tremendous growth in these years. The developement of techniques for the automatic management of such a bulk of information is becoming a key iussue. This report presents a survey of recent techniques for automatic picture indexing and their application to image retrieval, image reconstruction and spatial reasoning about the objects in the images. Our emphasis is on the 2D string approach,
