Abstract
We present a block-oriented method for design of a finite set of linear predictors using a clustering algorithm on a training set. The predictors are tested with DPCM and 2-D code excited linear prediction (2-D-CELP) coding systems using switched prediction. An improved 2-D-CELP system using variable block size (VB 2-D-CELP) is proposed.
