  • Abstract
    This paper presents the improvement of the reconstructed image quality when using Hilbert scan of the image sub-blocks prior to vector quantization stage. Two methods for image vector quantization have been considered: Linde-Buzo-Gray algorithm and Self-Organizing Map neural network.
