3.5.1. Wirkungsweise

Regularize geometry at a speed proportional to the local mean curvature value: this filter uses the mean curvature algorithm to blur the image preserving edges.

The Mean Curvature algorithm is described on Wikipedia.

3.5.2. Filteraufruf

You can find this filter in the image menu under Filters → Blur → Mean Curvature Blur…

	These options are described in Abschnitt 2, „Gemeinsame Funktionsmerkmale“.

Iterations

Increasing Iterations increases blur.
