Abstract
A similarity computation unit (130) derives a first probability P indicating that a first moving body appearing in the first video is the same as a second moving body appearing in the second video on the basis of similarity of feature value of the moving bodies. A non-appearance probability computation unit (140) derives a second probability Q indicating that the first moving body is not the same as the second moving body on the basis of an elapsed time after the first moving body exits from the first video. A person determination unit (150) determines whether the first moving body is the same as the second moving body by comparing the probability P and Q.
Claims15
An information processing system comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- receive inputs of videos captured by a plurality of imaging apparatuses;
- determine that a first moving body appearing in a first video captured by a first imaging apparatus among the plurality of imaging apparatuses and a second moving body appearing in a second video captured by a second imaging apparatus among the plurality of imaging apparatuses are the same based on a similarity between the first moving body appearing in the first video and the second moving body appearing in the second video and an elapsed time from a first time point when the first moving body disappears from the first video;
- and
- generate a monitor screen indicating whether or not the first moving body and the second moving body are the same in accordance with a result of the determination.
An information processing method performed by at least one computer, the method comprising:
- receiving inputs of videos captured by a plurality of imaging apparatuses;
- determining that a first moving body appearing in a first video captured by a first imaging apparatus among the plurality of imaging apparatuses and a second moving body appearing in a second video captured by a second imaging apparatus among the plurality of imaging apparatuses are the same based on a similarity between the first moving body appearing in the first video and the second moving body appearing in the second video and an elapsed time from a first time point when the first moving body disappears from the first video;
- and
- generating a monitor screen indicating whether or not the first moving body and the second moving body are the same in accordance with a result of the determination.
A non-transitory computer readable recording medium storing programs, the programs causing at least one computer to perform:
- receiving inputs of videos captured by a plurality of imaging apparatuses;
- determining that a first moving body appearing in a first video captured by a first imaging apparatus among the plurality of imaging apparatuses and a second moving body appearing in a second video captured by a second imaging apparatus among the plurality of imaging apparatuses are the same based on a similarity between the first moving body appearing in the first video and the second moving body appearing in the second video and an elapsed time from a first time point when the first moving body disappears from the first video;
- and
- generating a monitor screen indicating whether or not the first moving body and the second moving body are the same in accordance with a result of the determination.
