Abstract :
We suggest a new solution to the problem of high-quality image compression; a new algorithm for gray-level image compression in the case of wavelet transform is proposed. It is based on the idea of embedding a model of the human visual system directly inside the transform process in the multiresolution analysis. The mathematical aspect is described by Bertoluzza and Albanesi (see Proceedings of Conference Mathematical Imaging: Wavelet Applications in Signal and Image Processing II, p.39, 1994) and it is briefly reviewed. The coding method used in the compression scheme is described, followed by some examples of the experimental results we have obtained
