An Affine moment invariant for multi-component shapes
Jovisa Zunic, Milos Stojmenovic
We introduce an image based algorithmic tool for analyzing multi-component shapes here. Due to the generic concept of multi-component shapes, our method can be applied to the analy…
A characterization of 2-threshold functions via pairs of prime segments
Elena Zamaraeva, Jovisa Zunic
A -valued function on a two-dimensional rectangular grid is called threshold if its sets of zeros and ones are separable by a straight line. In this paper we study 2-thres…
Asymptotics of the number of 2-threshold functions
Elena Zamaraeva, Jovisa Zunic
A -threshold function on a rectangular grid of size is the conjunction of threshold functions on the same domain. In this paper, we focus on the case and…
Errata to: the limiting curve of Jarnik's polygons
Jovisa Zunic
In this note we point out that the limit shape of the Jarnk polygonal curve [1] is the circle, not a curve consisting of arcs of parabolas as it has been stated in the main result…
