Median Filter
Median Filter softens fine noise and speckling while keeping edges reasonably intact, using a box-blur pass in discrete strength steps rather than a continuous slider.
Parameters
| Parameter | Type | Options | Default | What it does |
|---|---|---|---|---|
| Size | number | 3, 5, or 7 | 3 | Kernel size — larger values smooth more aggressively. |
Note: despite the name, this filter is implemented as a box blur rather than a true statistical median filter — it's a fast, effective noise-smoothing pass, just not the exact algorithm the name suggests.
