A method to detect inactive periods in animal movement using density-based clustering

In this paper, we propose a method to find inactive periods of a trajectory and employ it to livestock tracking. In contrast to the existing methods to find inactive periods in the domain of animal movement studies, the proposed method estimates inactive periods based on the position recordings only, without involving information from activity sensors or field,observations. The only parameter that the proposed method requires is the minimum duration of inactivity. Inactivity means being stationary or having limited variation in position. The results have been verified by applying the method to a dataset where activity sensor recordings are also available. (C) 2016 Elsevier Ltd. All rights reserved.
