### 3.5. Mean Curvature Blur

#### 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…

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

Iterations

  Increasing Iterations increases blur.
