Automatic detection of zones of interest in a video

Abstract

A method at a computing system includes obtaining video of an environment including a plurality of objects; defining a zone including a portion of the environment; subsequent to the defining, detecting a motion event captured in the video occurring at least partially within the zone, wherein the motion event is associated with a first object of the plurality of objects; identifying an object type of the first object; and based on the object type of the first object, causing a notification of the motion event to be issued or not issued.

         4 . The method of  claim 1 , wherein defining the zone includes identifying a source zone and/or a sink zone in a field of view included in the video. 
     
     
         5 . The method of  claim 4 , wherein identifying a source zone comprises:
 determining a number of the motion events that originated from a first region of the field of view within a predefined period of time;   determining whether the number of originated motion events exceeds a first predefined threshold; and   in accordance with a determination that the number of originated motion events exceeds the first predefined threshold, identifying the region of the field of view as a source zone.   
     
     
         6 . The method of  claim 4 , wherein identifying a sink zone comprises:
 determining a number of the motion events that terminated at a second region of the field of view within a predefined period of time;   determining whether the number of terminated motion events exceeds a second predefined threshold; and   in accordance with a determination that the number of terminated motion events exceeds the second predefined threshold, identifying the region of the field of view as a sink zone.   
     
     
         7 . A computing system, comprising:
 one or more processors;   one or more memory components; and   one or more programs stored in the one or more memory components and configured for execution by the one or more processors, the one or more programs comprising instructions for:
 obtaining video of an environment including a plurality of objects; 
 defining a zone including a portion of the environment; 
 subsequent to the defining, detecting a motion event captured in the video occurring at least partially within the zone, wherein the motion event is associated with a first object of the plurality of objects; 
 identifying an object type of the first object; and 
 based on the object type of the first object, causing a notification of the motion event to be issued or not issued. 
   
     
     
         8 . The computing system of  claim 7 , wherein the object type of the first object is identified as a person; and the one or more programs comprise instructions for:
 causing the notification of the motion event to be issued based on the object type of the first object being a person.   
     
     
         9 . The computing system of  claim 7 , wherein the object type of the first object is identified as an object other than a person; and the one or more programs comprise instructions for:
 causing the notification of the motion event to not be issued based on the object type of the first object being other than a person.   
     
     
         10 . The computing system of  claim 7 , wherein the instructions for defining the zone include instructions for identifying a source zone and/or a sink zone in a field of view included in the video. 
     
     
         11 . The computing system of  claim 10 , wherein the instructions for identifying a source zone comprise instructions for:
 determining a number of the motion events that originated from a first region of the field of view within a predefined period of time;   determining whether the number of originated motion events exceeds a first predefined threshold; and   in accordance with a determination that the number of originated motion events exceeds the first predefined threshold, identifying the region of the field of view as a source zone.   
     
     
         12 . The computing system of  claim 10 , wherein the instructions for identifying a sink zone comprise instructions for:
