In this paper, the Radon transform is used to design a new descriptor called Phi-signature invariant to usual geometric transformations. Experiments show the effectiveness of the m...
Topological predicates, as derived from the 9-intersection model, have been widely recognized in GIS, spatial database systems, and many other geo-related disciplines. They are ba...

A new combinatorial characterization of a gray-tone image called Euler Vector is proposed. Euler number of a binary image is a well-known topological feature, which remains invari...

We present a methodology to automatically construct robust signatures whose accuracy is based on formal reasoning so it can be systematically evaluated. Our methodology is based o...
Abstract. We show that under the assumptions of Spectrum Exchangeability and Language Invariance the so called Only Rule, a principle of instantial relevance previously know for un...
