Alert directives and focused alert directives in a behavioral recognition system

Abstract

Alert directives and focused alert directives allow a user to provide feedback to a behavioral recognition system to always or never publish an alert for certain events. Such an approach bypasses the normal publication methods of the behavioral recognition system yet does not obstruct the system's learning procedures.

1 . A method, comprising:
 obtaining characteristic values for an observed event in a scene,   parsing a plurality of alert directives to identify a matching alert directive from the plurality of alert directives based on the characteristic values corresponding to a range of criteria values of the matching alert directive, the matching alert directive overriding an alert publication procedure of a behavioral recognition system, and   upon identifying the matching alert directive, one of publishing or not publishing an alert, based on the overriding.   
     
     
         2 . The method of  claim 1 , wherein the characteristic values include at least one of: a pixel-height value, a pixel-width value, and an x- and y-coordinate center position of a foreground object. 
     
     
         3 . The method of  claim 1 , wherein the characteristic values include a set of x-coordinates and y-coordinates corresponding to a foreground object trajectory. 
     
     
         4 . The method of  claim 1 , wherein the matching alert directive includes a focus mask that intersects with a region in the scene where the observed event occurred. 
     
     
         5 . The method of  claim 1 , wherein the range of criteria values is adjustable via a graphical editor. 
     
     
         6 . (canceled) 
     
     
         7 . The method of  claim 1 , wherein the parsing the plurality of alert directives includes matching an object type and a behavior. 
     
     
         8 . A computer-readable storage medium storing instructions that when executed on a processor, perform an operation comprising:
 obtaining characteristic values for an observed event in a scene,   parsing a plurality of alert directives to identify a matching alert directive from the plurality of alert directives based on the characteristic values corresponding to a range of criteria values of the matching alert directive, the matching alert directive overriding an alert publication procedure of a behavioral recognition system, and   upon identifying the matching alert directive, one of publishing or not publishing an alert, based on the overriding.   
     
     
         9 . The computer-readable storage medium of  claim 8 , wherein the characteristic values include at least one of: a pixel-height value, a pixel-width value, and an x- and y-coordinate center position of a foreground object. 
     
     
         10 . The computer-readable storage medium of  claim 8 , wherein the characteristic values include a set of x-coordinates and y-coordinates corresponding to a foreground object trajectory. 
     
     
         11 . The computer-readable storage medium of  claim 8 , wherein the matching alert directive includes a focus mask that intersects with a region in the scene where the observed event occurred. 
     
     
         12 . The computer-readable storage medium of  claim 8 , wherein the range of criteria values is adjustable via a graphical editor. 
     
     
         13 . (canceled) 
     
     
         14 . The computer-readable storage medium of  claim 8 , wherein the parsing the plurality of alert directives includes matching an object type and a behavior. 
     
     
         15 . A system comprising:
 a processor and   a memory hosting an application, which, when executed on the processor, performs an operation for alerting a user to behavior corresponding to an alert directive, the operation comprising:
 obtaining characteristic values for an observed event in a scene, 
 parsing a plurality of alert directives to identify a matching alert directive from the plurality of alert directives based on the characteristic values corresponding to a range of criteria values of the matching alert directive, the matching alert directive overriding an alert publication procedure of a behavioral recognition system, and 
 upon identifying the matching alert directive, one of publishing or not publishing an alert, based on the overriding. 
   
     
     
         16 . The system of  claim 15 , wherein the characteristic values include at least one of: a pixel-height value, a pixel-width value, and an x- and y-coordinate center position of a foreground object. 
     
     
         17 . The system of  claim 15 , wherein the characteristic values include a set of x-coordinates and y-coordinates corresponding to a foreground object trajectory. 
     
     
         18 . The system of  claim 15 , wherein the matching alert directive includes a focus mask that intersects with a region in the scene where the observed event occurred. 
     
     
         19 . The system of  claim 15 , wherein the range of criteria values is adjustable via a graphical editor. 
     
     
         20 . (canceled) 
     
     
         21 . The system of  claim 15 , wherein the parsing the plurality of alert directives includes matching an object type and a behavior.
