We consider \emph{Alternating Direction Implicit} (ADI) splitting schemes tocompute efficiently the numerical solution of the PDE osmosis model consideredby Weickert et al. for several imaging applications. The discretised scheme isshown to preserve analogous properties to the continuous model. The dimensionalsplitting strategy traduces numerically into the solution of simple tridiagonalsystems for which standard matrix factorisation techniques can be used toimprove upon the performance of classical implicit methods, even for large timesteps. Applications to the shadow removal problem are presented.
