Anomalous stationary object detection and reporting

A computer-implemented method, comprising:

• analyzing, via one or more processors, an input stream of captured video frames, the captured video frames defining at least one scene, the captured video frames including a corresponding bounding box(es) for objects within the captured video frames;
• determining, via the one or more processors, whether an object within the captured video frames has remained at a specified location in the at least one scene for at least a threshold period;
• determining, via the one or more processors, whether the object has remained substantially stationary within the at least one scene during the threshold period;
• upon determining that the object has remained substantially stationary and remained within the at least one scene for at least the threshold period, determining, via the one or more processors, a rareness score for the object, the rareness score determined based at least in part on a number of intersection pixels of the object's corresponding bounding box(es), union of pixels covered by the object's corresponding bounding box(es) during tracking period, and a change in size of the object's corresponding bounding box(es);
• and
• generating, via the one or more processors, an alert upon determining the rareness score exceeds a threshold.
