Abstract

The analysis of image coding using Periodic Walsh Piecewise-Linear (PWL) transform will be presented in this paper. The coding method employs an integer bit allocation scheme and Llyod-Max quantizers. Experimental results have shown that best results are obtained by modeling the dc coefficient using a one-sided Gaussian distribution and the ac coefficients… (More)
