# Mean Curvature Blur

## Overview

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.

## Activating the Filter

This filter is found in the main menu under Filters Blur Mean Curvature Blur… .

## Options

Mean Curvature Blur filter parameters

Presets, Input Type, Clipping, Blending Options, Preview, Split view
Iterations

  Increasing Iterations increases blur.

## Examples

Original image

Iterations = 4

Mean Curvature Blur can be used to denoise an image:
