Another reference to PRML I presume?
To this page, I'd add a direct link to Mahalanobis Distance. I was just harping about MD in some HN comments the other day on a Bayes article. There's no pictoral representation on the wiki page, but it is intuitive and its one of those simple concepts with foundational implications.
MD rests on the assumption of gaussian/normal population. The math is straightforward, starting with the covariance matrix. The original (Rubine 1991) gesture recognizer used the MD of some 16 feature vectors between an input gesture and the collection of trained gestures.
