Abstract

The DCT zonal coding compares unfavorably with the DCT threshold coding, in respect of coding performances. This is due to quantization losses of the Max quantizer caused by long-tailed distributions of DCT coefficients. This paper proposes a method to compensate for the losses and to improve performances of the zonal coding, by applying M-transformation to the DCT coefficient sample sequences. Simulation results have shown the attained improvements remarkable.
