INFORMATION PROCESSING APPARATUS, CONTROL METHOD, AND PROGRAM
An information processing apparatus ( 2000 ) detects a stationary object from video data ( 12 ). In addition, the information processing apparatus ( 2000 ) executes person detection process of detecting a person in vicinity of an object (target object) detected as the stationary object for each of a plurality of video frames ( 14 ) which includes the target object. Furthermore, the information processing apparatus ( 2000 ) executes a predetermined process by comparing results of the person detection process for each of the plurality of video frames ( 14 ).

wherein the second video frame is captured chronologically before the first video frame.
8 . The information processing system according to claim 1 ,
wherein the object is detected as being placed and stationary.
9 . The information processing system according to claim 1 ,
wherein the object is detected as stationary in a case where a variation amount of the object is equal to or less than a predetermined value.
10 . The information processing system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
process the first video frame and the second video frame to extract, for each video frame, a feature value from a region where the human is detected; and
determine whether a same human is detected based on respective feature values extracted from the first video frame and the second video frame.
11 . The information processing system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
determine whether a human who has placed the target object exists in a vicinity of the target objects; and
issue a warning in response to determining that the human who has placed the target object does not exist in the vicinity of the target object.
12 . The information processing method according to claim 3 , further comprising
wherein the video frame includes a first video frame and a second video frame, the first video frame including the object and the part of the human, the second video frame including the object, and
wherein the second video frame is captured chronologically before the first video frame.
13 . The information processing method according to claim 3 ,
wherein the object is detected as being placed and stationary.
14 . The information processing method according to claim 3 ,
wherein the object is detected as stationary in a case where a variation amount of the object is equal to or less than a predetermined value.
15 . The information processing method according to claim 3 , further comprising:
processing the first video frame and the second video frame to extract, for each video frame, a feature value from a region where the human is detected; and
determining whether a same human is detected based on respective feature values extracted from the first video frame and the second video frame.
16 . The information processing method according to claim 3 , further comprising
determining whether a human who has placed the target object exists in a vicinity of the target object; and
issuing a warning in response to determining that the human who has placed the target object does not exist in the vicinity of the target object.
