3.5. Mean Curvature Blur

3.5. Mean Curvature Blur
	3. ぼかしフィルター

3.5.1. 概観

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. フィルターの呼び出し方

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

Iterations

Increasing Iterations increases blur.
