A syntactic approach to scale-space-based corner description
Cornelia Fermüller, Walter G. Kropatsch · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1994
Planar curves are described by information about corners integrated over various levels of resolution. The detection of corners takes place on a digital representation. To compensate for ambiguities arising from sampling problems due to the discreteness, results about the local behavior of curvature extrema in continuous scale-space are employed.>
