Method and System for Non-Causal Zone Search in Video Monitoring
First Claim
1. A method of facilitating review of a video recording, comprising:
- processing the video recording to identify a plurality of motion events, each motion event corresponding to a respective video segment along a timeline of the video recording, and identifying at least one object in motion within a scene depicted in the video recording;
storing a respective event mask for each of the plurality of motion events identified in the video recording, the respective event mask including an aggregate of motion pixels associated with the at least one object in motion in multiple frames of the motion event;
receiving a definition of a zone of interest within the scene depicted in the video recording; and
in response to receiving the definition of the zone of interest;
determining, for each of the plurality of motion events, whether the respective event mask of the motion event overlaps with the zone of interest by at least a predetermined overlap factor; and
identifying one or more events of interest from the plurality of motion events, wherein the respective event mask of each of the identified events of interest is determined to overlap with the zone of interest by at least the predetermined overlap factor; and
identifying at least one motion event from the one or more identified events of interest, the identified at least one motion event including at least one object in motion satisfying one or more object features, wherein the one or more object features include physical features characterizing the object in motion.

Abstract
A computing system processes a video recording to identify a plurality of motion events, each corresponding to a respective video segment along a timeline of the video recording. The computing system identifies at least one object in motion within a scene depicted in the video recording and stores a respective event mask for each event. The computing system receives a definition of a zone of interest within the scene. In response to receiving the definition, the computing system determines, for each motion event, whether the respective event mask of the motion event overlaps with the zone of interest by at least a predetermined overlap factor, and identifies one or more events of interest from the plurality of motion events, wherein the respective event mask of each identified event of interest is determined to overlap with the zone of interest by at least the predetermined overlap factor.

8. A computing system for facilitating review of a video recording, comprising:
-
one or more processors; and memory having instructions stored thereon, the instructions, when executed by the one or more processors, cause the processors to perform operations comprising; processing the video recording to identify a plurality of motion events, each motion event corresponding to a respective video segment along a timeline of the video recording, and identifying at least one object in motion within a scene depicted in the video recording; storing a respective event mask for each of the plurality of motion events identified in the video recording, the respective event mask including an aggregate of motion pixels associated with the at least one object in motion in multiple frames of the motion event; receiving a definition of a zone of interest within the scene depicted in the video recording; and in response to receiving the definition of the zone of interest; determining, for each of the plurality of motion events, whether the respective event mask of the motion event overlaps with the zone of interest by at least a predetermined overlap factor; and identifying one or more events of interest from the plurality of motion events, wherein the respective event mask of each of the identified events of interest is determined to overlap with the zone of interest by at least the predetermined overlap factor; and identifying at least one motion event from the one or more identified events of interest, the identified at least one motion event including at least one object in motion satisfying one or more object features, wherein the one or more object features include physical features characterizing the object in motion. - View Dependent Claims (9, 10, 12, 13, 14)
