Abstract: Indoor positioning system plays a key role in location-based services since the widely used global navigation satellite system (GNSS) is denied in indoor scenarios. Crowdsensing or walking-surveying-based indoor positioning is proposed aiming at providing low-cost… read more here.

Abstract: Currently, the most widely used point trajectories generation methods estimate the trajectories from the dense optical flow, by using a consistency check strategy to detect the occluded regions. However, these methods will miss some important… read more here.

Abstract: In this paper, we propose abnormal behavior detection algorithms based on dense trajectories and principal components for video surveillance applications. The result shows that the proposed algorithms are faster than an algorithm based on lengths… read more here.
