The number of continuous curves in digital geometry

Shiva Samieinia[1]

(1) Uppsala University, Sweden

As a model for continuous curves in digital geometry, we study the Khalimsky-continuous functions defined on the integers and with values in the set of integers or the set of natural numbers. We determine the number of such functions on a given interval. It turns out that these numbers are related to the Delannoy and Schröder arrays, and a relation between these numbers is established.

Keywords: Digital geometry, Khalimsky topology, Khalimsky plane, Khalimsky-continuous function
