# 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.
|
||
|
||
## Inputs
|
||
|
||
| Name | Type | Required | Description |
|
||
|------|------|----------|-------------|
|
||
| field | DATA_FIELD | Yes | Input field with scan scars |
|
||
|
||
## Outputs
|
||
|
||
| Name | Type | Description |
|
||
|------|------|-------------|
|
||
| corrected | DATA_FIELD | Field with scars removed and interpolated |
|
||
| scar_mask | IMAGE | Binary mask of the detected scar pixels |
|
||
|
||
## Controls
|
||
|
||
| Name | Type | Default | 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) |
|
||
|
||
## Limitations
|
||
|
||
- Designed for horizontal (fast-scan) scars only; vertical scars are not detected.
|
||
- Aggressive thresholds may remove legitimate surface features that resemble scars.
