Video content activity context and regions

A method of operating a video camera system, the method comprising:

• recording, using a video capture element and an electronic media storage device controlled by one or more processors, video frames of a scene captured by the video capture element, wherein the scene includes a zone defined as an area within a field-of-view of the video capture element;
• performing, by the one or more processors, a first analysis of a first set of the recorded video frames showing the zone over a first period of time and a second set of the recorded video frames showing the zone over a second period of time;
• determining by the one or more processors, based on the first analysis, a first difference of composition between the first set of video frames and the second set of video frames within the zone;
• performing, by the one or more processors, a second analysis of a third set of the recorded video frames showing an area outside of the zone over a third period of time and a fourth set of the recorded video frames showing the area outside of the zone over a fourth period of time;
• determining by the one or more processors, based on the second analysis, a second difference of composition between the third set of video frames and the fourth set of video frames;
• characterizing, by the one or more processors, one or more properties corresponding to the second difference in composition outside of the zone;
• determining, by the one or more processors, whether the one or more properties are associated with the first difference in composition within the zone;
• and
• in response to determining that the one or more properties are associated with the first difference in composition within the zone, the one or more processors are configured to perform:
• characterizing the first difference in composition within the zone based on the one more properties;
• and
• performing an action based on the characterization of the first difference in composition within the zone.

A non-transitory computer-program product tangibly embodied in a machine-readable non-transitory storage medium that includes instructions configured to cause one or more processors to:

• record, using a video capture element and an electronic media storage device, video frames of a scene captured by the video capture element, wherein the scene includes a zone defined as an area within a field-of-view of the video capture element;
• perform a first analysis of a first set of the recorded video frames showing the zone over a first period of time and a second set of the recorded video frames showing the zone over a second period of time;
• determine, based on the first analysis, a first difference of composition between the first set of video frames and the second set of video frames within the zone;
• perform a second analysis of a third set of the recorded video frames showing an area outside of the zone over a third period of time and a fourth set of the recorded video frames showing the area outside of the zone over a fourth period of time;
• determine, based on the second analysis, a second difference of composition between the third set of video frames and the fourth set of video frames;
• characterize one or more properties corresponding to the second difference in composition outside of the zone;
• determine whether the one or more properties are associated with the first difference in composition within the zone;
• and
• in response to determining that the one or more properties are associated with the first difference in composition within the zone, the one or more processors are configured to:
• characterize the first difference in composition within the zone based on the one more properties;
• and
• perform an action based on the characterization of the first difference in composition within the zone.
