Automatic least-squares projection of points onto point clouds with applications in reverse engineering
A novel method for projecting points onto a point cloud, possibly with noise, is presented based on the point directed projection (DP) algorithm proposed by Azariadis P., Sapidis ...

Singular Curves in the Joint Space and Cusp Points of 3-RPR parallel manipulators
This paper investigates the singular curves in the joint space of a family of planar parallel manipulators. It focuses on special points, referred to as cusp points, which may app...

Hybrid curve fitting
We consider a parameterized family of closed planar curves and introduce an evolution process for identifying a member of the family that approximates a given unorganized point cl...

Projective Estimators for Point/Tangent Representations of Planar Curves
Recognizing shapes in multiview imaging is still a challenging task, which usually relies on geometrical invariants estimations. However, very few geometric estimators that are pro...

Computing a Lower Bound for the Canonical Height on Elliptic Curves over Q
Let E be an elliptic curve over the rationals. A crucial step in determining a Mordell-Weil basis for E is to exhibit some positive lower bound > 0 for the canonical height ^h ...
