Fj. Gonzalez-castano et al., Fast image recovery using dynamic load balancing in parallel architectures, by means of incomplete projections, IEEE IM PR, 10(4), 2001, pp. 493-499
This paper formulates an incomplete projection algorithm that is applied to
the image recovery problem. The algorithm allows an easy implementation of
dynamic load balancing for parallel architectures. Furthermore, the local
computation - communication load ratio can be adjusted, since each processo
r performs a finite number of iterations of any projection-type technique,
and this number can be provided as a parameter of the algorithm. Numerical
results compare favorably with those obtained by the extrapolated method of
parallel subgradient projections.
