Scar Removal
Detect and remove horizontal scan scars using Gwyddion-derived scar marking thresholds, then interpolate over the detected mask with a Laplace-style inpaint.

Description |
| scar_type |
dropdown |
both |
Which scar polarity to detect: both, positive (bright), or negative (dark) |
| threshold_high |
FLOAT |
0.666 |
High threshold relative to local RMS for strong scar detection (0–2) |
| threshold_low |
FLOAT |
0.25 |
Low threshold for extending already-detected scars (0–2) |
| min_length |
INT |
16 |
Minimum horizontal run length in pixels to classify as a scar (1–4096) |
| max_width |
INT |
4 |
Maximum vertical width in pixels for a scar candidate (1–32) |
Notes
- Designed for horizontal (fast-scan) scars only; vertical scars are not detected.
- Aggressive thresholds may remove legitimate surface features that resemble scars.
