Summary:

This paper deals with the high curvature points of curves, and uses derivatives to calculate curve maxima.

Discussion:

Our application requires us to be able to gauge the similarity between two freely drawn curves, and we expect a very optimistic approximation of correctness between a template and candidate curve in the case of rivers.

Although the curve detection methods presented here are for a computer vision domain, they can be easily translated to the sketch domain.
