Terms from Artificial Intelligence: humans at the heart of algorithms

Page numbers are for draft copy at present; they will be replaced with correct numbers when final book is formatted. Chapter numbers are correct and will not change now.

A Gaussian filter applies a convolution to the image with a Normal distribution. This has the effect of smoothing the image, rather like looking with your eyes screwed up. Increasing the standard deviation of the Normal distribution increases the level of smearing.

Used in Chap. 12: pages 178, 179, 183, 196

Gaussian filter with σ = 0.8
