Method and Apparatus for Acquiring Information

An apparatus for acquiring information, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• acquiring images of a plurality of unregistered users, the unregistered users being users having no registered images belonging to the unregistered users in a face recognition system;
• calculating a maximum similarity corresponding to an image of each unregistered user in the images of the plurality of unregistered users, the maximum similarity being a maximum similarity among similarities between a face object in the image of the unregistered user and face objects in a plurality of registered images in the face recognition system;
• and
• determining a similarity threshold corresponding to a preset condition based on the calculated maximum similarity corresponding to the image of the each unregistered user, the preset condition comprising a ratio of a number of images of the unregistered users with corresponding maximum similarities greater than the similarity threshold in the images of the plurality of unregistered users to a number of the images of the plurality of unregistered users being smaller than a ratio threshold.

A non-transitory computer storage medium storing a computer program, the computer program when executed by one or more processors, causes the one or more processors to perform operations, the operations comprising:

• acquiring images of a plurality of unregistered users, the unregistered users being users having no registered images belonging to the unregistered users in a face recognition system;
• calculating a maximum similarity corresponding to an image of each unregistered user in the images of the plurality of unregistered users, the maximum similarity being a maximum similarity among similarities between a face object in the image of the unregistered user and face objects in a plurality of registered images in the face recognition system;
• and
• determining a similarity threshold corresponding to a preset condition based on the calculated maximum similarity corresponding to the image of the each unregistered user, the preset condition comprising a ratio of a number of images of the unregistered users with corresponding maximum similarities greater than the similarity threshold in the images of the plurality of unregistered users to a number of the images of the plurality of unregistered users being smaller than a ratio threshold.
