| Abstract: | Abstract: "Although the widely-used Perona-Malik filter is regarded as ill-posed, straightforward implementations are often surprisingly stable. We give an explanation for this effect by applying a discrete nonlinear scale-space framework: a spatial discretization on a fixed pixel grid gives a well-posed scale-space with many image-simplifying properties, and an explicit time discretization leads to a scheme which does not introduce additional oscillations. This explains why staircasing is essentially the only practically appearing instability." |
