impulse | transfer function (scaled, bipolar) |
no clipping | clip at abs(z)=10 |

The method described in the textbook seems to be from
Sondhi, M.M. [1972]. "Image Restoration: The Removal of Spatially Invariant Degradations", Proc. IEEE, vol. 60, no. 7, pp. 842-853.
The example below was produced with a blur of 32 pixels (1/8 of image width).
