Description
This effect/filter detects and draws edges using the Canny edge detection algorithm[1].
Parameters
Parameter |
Value |
Description |
|---|---|---|
Low / High threshold |
Float |
Set low and high threshold values used by the algorithm. The High threshold selects the „strong“ edge pixels, which are then connected through 8-connectivity with the „weak“ edge pixels selected by the Low threshold. Range is from 0.000 to 1.000 with Low threshold being lower or equal to High threshold. |
Modes |
Selection |
Define the drawing mode |
Planes |
Selection |
Select the planes for filtering |
The following selection items are available:
Modes
Wires |
Draw white/gray wires on black background (default) |
Colormix |
Mix the colors to create a paint/cartoon effect |
Canny |
Applies Canny edge detector on all selected planes |
Planes
