1. An information processing apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
in a predetermined area where a plurality of cameras are installed along a path, where the cameras respectively have first tables,
extract registered first feature information from a person included in a first image generated at a first time by a first camera of the cameras along the path, and store the registered first feature information in the first table of the first camera, the registered first feature information including a feature of a region other than a face;
perform, for each camera other than the first camera, a first collation process of collating first feature information extracted from a person included in a second image generated after the first timing by the each camera with the first registered feature information, to acquire a first collation result;
for each camera other than the first camera, determine, in a case where the first collation result indicates a match, that the person corresponds to the first registered feature information and store the first feature information of the person in the first table of the each camera in association with date and time information of the determination-when the person is determined;
perform a second collation process of collating second feature information extracted from the person with second registered feature information to acquire a second collation result, the second feature information being face feature information;
for each camera for which the first feature information extracted from the person has been stored in the first table of the each camera, integrate the first feature information and store the integrated first feature information in association with the second collation result in a second table; and
in case where the second collation result in the second table indicates a mismatch after the second collation process has been performed using the second image generated by a last camera of the cameras along the path, output an alert regarding the person.
