Gaussian filter

Terms from Artificial Intelligence: humans at the heart of algorithms

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.
