Edge Detect
Edge Detect
Use Edge Detect to isolate luminance boundaries as clean line masks. It is often paired with blur or threshold for stylized contour effects.
Availability
This node requires Pro.
Common uses
- Use analysis outputs as masks or support maps in blend chains.
- Pair with levels or threshold nodes to isolate useful map ranges.
Input ports
-
input -
Usually expects a structured grayscale or height-like input.
Output ports
-
out -
Outputs one or more analysis maps depending on node type.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Edge Width | float | 1 | 1 to 16 |
| Edge Roundness | float | 0 | 0 to 16 |
| Tolerance | float | 0.05 | 0 to 1 |
| Invert | bool | false | - |
Behavior
- These nodes compute derived data from shape and height information.
- Outputs are often best consumed by downstream utility and mixing nodes.
Common mistakes
- Analysis nodes can be sensitive to noisy or low-contrast inputs.
- Map interpretation changes with downstream color-space assumptions.
