(Elsevier, 2014-01-22)
Given an infinite word x over an alphabet A, a letter b occurring in

The problem presented in this paper is how to find similarities between digital images useful in design cybernetic vision systems. The solution to this problem stems from a neighbourhood based vision system. A neighbourhood ...
Attainable lengths for circular binary words avoiding k-powers
(The Belgian Mathematical Society, 2005)
We show that binary circular words of length n avoiding 7/3+ powers exist
for every sufficiently large n. This is not the case for binary circular words
avoiding k+ powers with k < 7/3

(2013-05-28)
In this work, we analyze some of the existing secret image sharing methods and show that they do not possess
indistinguishability, a property of many secure systems. We propose a new method based on the $(k, n)$ threshold ...
