Abstract

METHODS AND APPARATUSES FOR SEARCHING FOR TARGET PERSON, DEVICES, PROGRAM PRODUCTS, AND MEDIA 5 Embodiments of the present disclosure provide methods and apparatuses for searching for a target person, devices, program products, and media, and improve the accuracy rate of searching for a target person. The method includes: obtaining an image of the target person; searching a face image l ibrary by using the image of the 10 target person to obtain a first face image template matching the image of the target person, where the face image library includes a plurality of face image templates; and obtaining, according to the first face image template and a pedestrian image library, at least one target pedestrian image template matching the image of the target person, where the pedestrian image library includes a plurality of pedestrian image templates. 15 [Figure 1]
