Abstract:
Techniques are disclosed for analyzing a scene depicted in an input stream of video frames captured by a video camera. The techniques include receiving data for an object within the scene and determining whether the object has remained substantially stationary within the scene for at least a threshold period. If the object is determined to have remained stationary for at least the threshold period, a rareness score is calculated for the object to indicate a likelihood of the object being stationary to an observed degree at an observed location. The rareness score may use a learning model to take into account previous stationary and/or non-stationary behavior of objects within the scene. In general, the learning model may be updated based on observed stationary and/or non-stationary behaviors of the objects. If the rareness score meets reporting conditions, the stationary object event may be reported.

Claim (Index 6):
The computer-implemented method of  claim 1 , further comprising:\n storing a list of substantially stationary objects no longer visible in the scene; upon detecting that a new object appears from behind a second object, comparing the new object to the substantially stationary objects in the list; and upon determining the new object matches one of the substantially stationary objects in the stored list, adding time the new object is substantially stationary before leaving the scene, time between the new object leaving the scene and appearing from behind the second object, and time during which the new object is substantially stationary after appearing from behind the other object, to obtain the time the new object has remained at an observed location in the scene.
