abstract = "In this paper, we propose different criteria for detecting unusual
motion in surveillance cameras. Initially, a certain environment
is observed within a time interval, and captured trajectories are
used as examples of usual trajectories. These trajectories are
used to build a Spatial Occupancy Map (SpOM, which is introduced
in this paper) of the observed people, as well as main flow
directions. In the test period, each new trajectory is classified
as normal or unusual with respect to spatial occupancy and
trajectory consistency. The spatial occupancy criterion considers
the relation of space occupancy between the new tracked trajectory
and the observed period. The trajectory consistency criterion
considers the agreement of the new trajectory with the main flows
extracted in the training period. Experimental results showed that
these criteria can be used as an automatic pre-screening of
suspect motion in surveillance applications.",
