# Zero Mean
|
|
|
|
Shift all values so the mean is exactly zero. A pure offset subtraction — no plane fit or polynomial involved.

## Outputs

## Notes
|
|
|
|
- Equivalent to subtracting a constant (the mean) from every pixel.
|
|
- Does not change relative height differences — only shifts the overall offset.
