Towards a geometric interpretation of double-cross matrix-based similarity of polylines
One of the formalisms to qualitatively describe polylines in the plane are double-cross matrices. In a double-cross matrix the relative position of any two line segments in a poly...

Qualitative polyline similarity testing with applications to query-by-sketch, indexing and classification
We present an algorithm for polyline (and polygon) similarity testing that is based on the double-cross formalism. To determine the degree of similarity between two polylines, the...
