	3. Filtros de desfocar

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

Presets, “Input Type”, Clipping, Blending Options, Preview, Split view

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

Iterations

Increasing Iterations increases blur.

3.5.4. Examples

Imagem original

Iterations = 4

Mean Curvature Blur can be used to denoise an image:
