Detecting similarity of rational plane curves
Alcazar, Juan Gerardo; Hermoso, Carlos; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2014)A novel and deterministic algorithm is presented to detect whether two given rational plane curves are related by means of a similarity, which is a central question in Pattern Recognition. As a by-product it finds all such ... -
Detecting symmetries of rational plane and space curves
Alcazar, Juan Gerardo; Hermoso, Carlos; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2014)This paper addresses the problem of determining the symmetries of a plane or space curve defined by a rational parametrization. We provide effective methods to compute the involution and rotation symmetries for the planar ... -
Similarity detection of rational space curves
Alcazar, Juan Gerardo; Hermoso, Carlos; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2017)We provide an algorithm to check whether two rational space curves are related by a similarity. The algorithm exploits the relationship between the curvatures and torsions of two similar curves, which is formulated in a ... -
Symmetry Detection of Rational Space Curves from their Curvature and Torsion
Alcazar, Juan Gerardo; Hermoso, Carlos; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2015)We present a novel, deterministic, and efficient method to detect whether a given rational space curve is symmetric. By using well-known differential invariants of space curves, namely the curvature and torsion, the method ...
