### 3.5. Mean Curvature Blur

#### 3.5.1. Visão-geral

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. Ativar o filtro

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

#### 3.5.3. Opções

  | Nota
  These options are described in Seção 2, “Common Features”.

Iterations

  Increasing Iterations increases blur.

#### 3.5.4. Examples
