Discovery of stay area in indoor trajectories of moving objects

作者：

Highlights：

• The stay area in trajectory of the indoor moving object is defined.

• A novel stability value-based algorithm is proposed for discovering the stay area.

• T - OPTICS is proposed to detect abnormal stay points in the discovered stay area.
