Abstract :
A 2-D lossless predictive coding system is implemented using several existing and recently proposed algorithms. These are also evaluated for autoregressive (AR) and autoregressive moving-average (ARMA) predictor models. Results are given, using test images, which allow that the choice of the algorithms and the model can significantly affect the compression factor
