| # | Feature | Gwyddion Source | Description |
|---|---------|---------------|-------------|
| 15 | Correlation / Pattern Matching | crosscor.c, maskcor.c | Find repeated features or align images via cross-correlation. |
| 16 | Slope Distribution | slope_dist.c | Angular histogram of surface slopes. Characterizes surface texture directionality. |
| 17 | Grain Filtering | grain_filter.c | Remove grains by size, height, or border contact. Refine grain masks post-detection. |
| 18 | Field Arithmetic | arithmetic.c | Add/subtract/multiply/divide two DATA_FIELDs. Useful for difference maps, normalization. |
