Information processing system, method and computer readable medium for determining whether moving bodies appearing in first and second videos are the same or not using histogram

An information processing method performed by at least one computer, the method comprising:

• receiving inputs of videos captured by a plurality of imaging apparatuses;
• detecting a first person in a first video captured by a first imaging apparatus among the plurality of imaging apparatuses and a second person in a second video captured by a second imaging apparatus among the plurality of imaging apparatuses;
• associating the first person with the second person, based on a first feature value of the first person and a second feature value of the second person;
• and
• providing an elapsed time based on first time information corresponding to the first person and second time information corresponding to the second person,
• wherein the first feature value and the second feature value include information based on a histogram.

A non-transitory computer readable recording medium storing programs executable by at least one computer to perform:

• receiving inputs of videos captured by a plurality of imaging apparatuses;
• detecting a first person in a first video captured by a first imaging apparatus among the plurality of imaging apparatuses and a second person in a second video captured by a second imaging apparatus among the plurality of imaging apparatuses;
• associating the first person with the second person, based on a first feature value of the first person and a second feature value of the second person;
• and
• providing an elapsed time based on first time information corresponding to the first person and second time information corresponding to the second person,
• wherein the first feature value and the second feature value include information based on a histogram.
