Abstract
An approach to image data compression using the 2-D lattice modelling method is presented. In addition to the 2-D lattice predictor, this realisation includes uniform quantisation and entropy coding of the prediction errors of the predictor. Results show that coded pictures with an signal/noise ratio of 30.5 dB can be obtained at an information rate of 0.8 bit/pixel.
