Laplacian-of-Gaussian filter

Terms from Artificial Intelligence: humans at the heart of algorithms

The glossary is being gradually proof checked, but currently has many typos and misspellings.

A Laplacian-of-Gaussian filter is simply a Laplacian operator applied after a Gaussian filter. By changing the standard deviation of the Gaussian filter, this combination identifies edges and regions at different levels of detail. This technique is applied in Marr's primal sketch, partly as an efficiency mechanism.
