Abstract :
The performances of the conventional CRC (conditional runlength code) and CIRC (conditional incremental runlength code) are improved with some modifications in coding algorithm. These include ZOH (zero-order hold) prediction, modified line-termination, and classification of the incremental runs. Average gains of 15% and 9% are obtained in compression factor for the CRC and CIRC, respectively.
