Explicit volume-preserving splitting methods for divergence-free ODEs by tensor-product basis decompositions (Oxford University PressInstitute of Mathematics and its Applications, 2014-02-23)We discuss the construction of volume-preserving splitting methods based on a tensor product of single-variable basis functions. The vector field is decomposed as the sum of elementary divergence-free vector fields (EDFVFs), ...Journal article
(Springer, 2011)The Beltrami flow is an efficient nonlinear filter, that was shown to be effective for color image processing. The corresponding anisotropic diffusion operator strongly couples the spectral components. Usually, this flow ...Peer reviewedJournal article
