An index is devised to support position-independent search for images containing quartets of icons. Point quartets exist that do not unambiguously map to quadrilaterals, however, ...
The Perspective-N-Point problem (PNP) is a notable problem in computer vision. It consists in, given N points known in an object coordinate space and their projection onto the ima...
Motivated by the desire to cope with data imprecision [8], we study methods for preprocessing a set of planar regions such that whenever we are given a set of points, each of whic...
A planar point set S is an (i, t) set of ghost chimneys if there exist lines H0, H1, . . . , Ht-1 such that the orthogonal projection of S onto Hj consists of exactly i + j distin...

The task of registering video frames with a static model is a common problem in many computer vision domains. The standard approach to registration involves finding point correspo...
