Some Properties of Entropies for change Detection

Abstract

The segmentation of signals is an important process in change detection applications. Many results reported in the literature use information and entropy, as direct or indirect processed variables. The objective of the paper is to make a short review of the similarities between Shannon and Renyi entropies, and the ways of using them in change detection problem. This paper is on signal description and analysis from information point of view, and it can be viewed as a practical short overview.
