On shape-preserving boundary conditions for diffusion smoothing
Emanuele Trucco · 2003
Several boundary treatments for attenuating shape deformation introduced by Gaussian smoothing are discussed. The author models Gaussian smoothing by a diffusion equation, a general mathematical framework particularly useful for scale-space analysis. An adaptive, shape-reserving boundary condition for diffusion smoothing range images is introduced. It is shown that this condition is more general than similar techniques found in the literature.>
