Box Blur
Box Blur
Use Box Blur to soften harsh transitions and average local detail quickly. It is often used to precondition masks before blending or displacement.
Availability
This node is available in the free feature set.
Common uses
- Use blur before thresholding to smooth noisy masks.
- Use sharpen and highpass to recover or isolate detail bands.
Input ports
-
input -
Requires an image input signal.
Output ports
-
out -
Outputs a filtered image that preserves graph connectivity.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Radius | float | 2 | 0 to 10 |
Behavior
- Detail filters operate on neighboring pixels and are sensitive to resolution.
- Different blur and sharpen algorithms produce distinct edge behavior.
Common mistakes
- Large radii can wipe out fine structure.
- Repeated detail filters can create halos or ringing.
