# Tip Deconvolution
|
|
|
|
Reconstruct the true surface from a tip-broadened measured AFM image. Uses morphological grey erosion (Villarrubia algorithm). Equivalent to gwy_tip_erosion (tip.c).

## Controls
|
|
|
|
None.

## Notes
|
|
|
|
- The tip pixel size must match the image pixel size exactly; mismatched calibrations will produce incorrect results.
|
|
- Deconvolution can only reduce tip broadening; it cannot recover information lost below the noise floor.
|
|
- Very large tip sizes are slow due to the nested loop over all tip pixels.
