Reducing Computation Time in a Reaction-Diffusion Stereo Algorithm

A reaction-diffusion stereo algorithm consists of multi-sets of reaction-diffusion equations. Since the equations are described with time-evolving partialdifferential equations, they require much computation time. In addition, the previous algorithm does not state any criterion for convergence judgement; we need to compute the equations for enough duration of time until their solutions converge. In this work, for reducing computation time in the algorithm, we propose a criterion for convergence judgement and implement the algorithm on a multiprocessor computer system.
