	3. Sløringsfiltra

3.5.1. Oversyn

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. Activating the Filter

This filter is found in the image window menu under Filters → Blur → Mean Curvature Blur….

	These options are described in Del 2, «Common Features».

Iterations

Increasing Iterations increases blur.
