    In this paper we address the problem of segmenting a trajectory such that each segment is in some sense homogeneous. We formally define different spatio-temporal criteria under which a trajectory can be homogeneous, including ...

    We study water flow computation on imprecise terrains. We consider two approaches to modeling flow on a terrain: one where water flows across the surface of a polyhedral terrain in the direction of steepest descent, and ...

  • Segmenting trajectories: A framework and algorithms using spatiotemporal criteria 

    Buchin, Maike; Driemel, Anne; Kreveld, Marc van; Sacristán Adinolfi, Vera (2011)
    Article
    Open Access
    In this paper we address the problem of segmenting a trajectory based on spatiotemporal criteria. We require that each segment is homogeneous in the sense that a set of spatiotemporal criteria are fulfilled. We define ...
