Meshfree particle method [PDF]

open access: yesProceedings Ninth IEEE International Conference on Computer Vision, 2003
Many of the computer vision algorithms have been posed in various forms of differential equations, derived from minimization of specific energy functionals, and the finite element representation and computation have become the de facto numerical strategies for solving these problems. However, for cases where domain mappings between numerical iterations
