Wavelet transform image coding using lattice vectorquantisation
Demetrios G. Sampson, Eduardo A. B. da Silva, M. Ghanbari · Electronics Letters · 1994
A novel method for the efficient coding of image wavelet coefficients using zerotree multistage lattice vector quantisation is presented. This method achieves high compression ratios with good picture quality, maintaining a very simple implementation. Simulation results demonstrate that the coding performance of this algorithm favourably compares to some of the best reported image compression results.
