Smooth by Domain Transform

An edge-preserving smoothing filter implemented with the Domain Transform recursive technique. Similar to a bilateral filter, but faster to compute.
Quality
Number of filtering iterations. A value between 2 and 4 is usually enough.
name: n-iterations type: int default: 3 minimum: 1 maximum: 5 ui-minimum: 1 ui-maximum: 5 ui-gamma: 1.00 ui-step-small: 1 ui-step-big: 2
Blur radius
Spatial standard deviation of the blur kernel, measured in pixels.
name: spatial-factor type: double default: 30.00 minimum: 0.00 maximum: 1000.00 ui-minimum: 0.00 ui-maximum: 1000.00 ui-gamma: 1.00 ui-step-small: 1.00 ui-step-big: 100.00 ui-digits: 1
Edge preservation
Amount of edge preservation. This quantity is inversely proportional to the range standard deviation of the blur kernel.
name: edge-preservation type: double default: 0.80 minimum: 0.00 maximum: 1.00 ui-minimum: 0.00 ui-maximum: 1.00 ui-gamma: 1.00 ui-step-small: 0.00 ui-step-big: 0.10 ui-digits: 3
