# Spot Removal
|
|
|
|
Fill defect pixels (hot pixels, dropouts, scan artifacts) by interpolation. The mask defines defect locations. Equivalent to Gwyddion spotremove.c.
|
|
|
|
## Inputs
|
|
|
|
| Name | Type | Required | Description |
|
|
|------|------|----------|-------------|
|
|
| field | DATA_FIELD | Yes | Input field with defect pixels |
|
|
| mask | IMAGE | No | Binary mask marking defect pixel locations; if omitted, no inpainting is performed |
|
|
|
|
## Outputs
|
|
|
|
| Name | Type | Description |
|
|
|------|------|-------------|
|
|
| result | DATA_FIELD | Field with defect pixels replaced by interpolated values |
|
|
|
|
## Controls
|
|
|
|
| Name | Type | Default | Description |
|
|
|------|------|---------|-------------|
|
|
| method | dropdown | laplace | Inpainting method: laplace (smooth Laplace equation solution), mean (local mean), or zero |
|
|
| max_iter | INT | 100 | Maximum number of iterations for the Laplace solver (1-2000) |
|
|
|
|
## Notes
|
|
|
|
- Large masked regions may not converge fully within max_iter iterations using the Laplace method.
|
|
- The mean method uses a simple neighbourhood average and may leave visible discontinuities at large defect clusters.
