Abnormality detection device and abnormality detection method

Abstract

An image processing device ( 100 ) includes a change detection unit ( 101 ) that detects a target state change in a person on the basis of an input image, and a determination unit ( 102 ) that determines an abnormal state in accordance with a detection obtained by detecting occurrences of the target state change in a plurality of persons.

1 . An image processing device comprising:
 one or more memories storing instructions; and   one or more processors configured to execute the instructions to:
 detect whether an input image includes a person in a predetermined state, the predetermined state being indicative of a predetermined changed state of the person corresponding to a type of an abnormal state; 
 determine an occurrence of the abnormal state when a plurality of persons in the predetermined state are detected in the input image; and 
 output an image with a drawing element attached to each group of person with the same type of abnormal state among the plurality of persons detected in the input image. 
   
     
     
         2 . The image processing device according to  claim 1 , wherein
 the one or more processors are configured to execute the instructions to:
 count a number of the plurality of persons detected in the same type of abnormal state in the input image; and 
 determine whether the counted number of the plurality of persons is equal to or more than a predetermined number. 
   
     
     
         3 . The image processing device according to  claim 1 , wherein
 the one or more processors are configured to execute the instructions to
 change drawing method of the drawing element in an area where a plurality of the drawing elements overlap. 
   
     
     
         4 . The image processing device according to  claim 2 , wherein
 the output image includes information indicating the number of persons in the group of person.   
     
     
         5 . An image processing method comprising:
 detecting whether an input image includes a person in a predetermined state, the predetermined state being indicative of a predetermined changed state of the person corresponding to a type of an abnormal state;   determining an occurrence of the abnormal state when a plurality of persons in the predetermined state are detected in the input image; and   outputting an image with a drawing element attached to each group of person with the same type of abnormal state among the plurality of persons detected in the input image.   
     
     
         6 . The image processing method according to  claim 5 , further comprising:
 counting a number of the plurality of persons detected in the same type of abnormal state in the input image; and   determining whether the counted number of the plurality of persons is equal to or more than a predetermined number.   
     
     
         7 . The image processing method according to  claim 5 , further comprising
 changing drawing method of the drawing element in an area where a plurality of the drawing elements overlap.   
     
     
         8 . The image processing method according to  claim 6 , wherein
 the output image includes information indicating the number of persons in the group of person.   
     
     
         9 . A non-transitory computer readable recording medium which records a program, wherein the program causing a computer to execute:
 detecting whether an input image includes a person in a predetermined state, the predetermined state being indicative of a predetermined changed state of the person corresponding to a type of an abnormal state;   determining an occurrence of the abnormal state when a plurality of persons in the predetermined state are detected in the input image; and   outputting an image with a drawing element attached to each group of person with the same type of abnormal state among the plurality of persons detected in the input image.   
     
     
         10 . The recording medium according to  claim 9 , wherein the program further causes the computer to execute:
 counting a number of the plurality of persons detected in the same type of abnormal state in the input image; and   determining whether the counted number of the plurality of persons is equal to or more than a predetermined number.   
     
     
         11 . The recording medium according to  claim 9 , wherein the program further causes the computer to execute:
 changing drawing method of the drawing element in an area where a plurality of the drawing elements overlap.   
     
     
         12 . The recording medium according to  claim 10 , wherein
 the output image includes information indicating the number of persons in the group of person.
