Document Type and Number:
WIPO Patent Application WO/2024/079777
Kind Code:
A1
Abstract:
An information processing system (100) comprises an analysis result acquisition unit (131), a candidate detection unit (132), and a missing child detection unit (134). The analysis result acquisition unit (131) acquires an analysis result of video captured by a plurality of video capturing devices (101). The candidate detection unit (132) uses a person attribute included in the analysis result and a candidate condition to detect missing child candidates from among persons captured in the video. The missing child detection unit (134) detects, when the missing child candidate has an accompanying person at a first time point, on the basis of a result of comparison between the accompanying person of the missing child candidate between this first time point and an accompanying person at a second time point earlier than this first time point, a missing child from among the missing child candidates.
