  • Abstract
    An efficient block-based coding scheme for noisy images is proposed. Unlike a conventional encoder where pre-filtering, discrete cosine transforms (DCT), quantisation, and variable length coding (VLC) are cascaded, the proposed image coder has only a modified DCT and a VLC and performs pre-filtering and quantisation simultaneously in the modified DCT operation
