F. Ancona et al., AN EFFICIENT TECHNIQUE FOR IMPLEMENTING AN IMAGE-COMPRESSION NEURAL ALGORITHM ON CONCURRENT MULTIPROCESSOR, Engineering applications of artificial intelligence, 10(6), 1997, pp. 573-580
The paper describes a pal-allel implementation of a neural algorithm p
erforming vector quantization for very low bit-rate video compression
on toroidal-mesh multiprocessors systems. The neural model considered
is a plastic version of the Neural Gas algorithm, whose features are s
uitable for implementations on toroidal mesh topologies. The architect
ure adopted and the data-allocation strategy enhance the method's scal
ing properties and remarkable efficiency. The parallel approach is sup
ported by a theoretical analysis of the efficiency of the overall stru
cture. Experimental results on a significant testbed and the fit betwe
en predicted and measured values confirm the validity of the parallel
approach. (C) 1998 Published by Elsevier Science Ltd All rights reserv
