A people counting system includes: a top-view, a first and a second side-view image-capturing device, capturing a top-view, a first and a second side-view image respectively; an image stitching module, stitching the top-view, the first and the second side-view image into an ultra wide-angle image; a ROI selecting module, selecting at least one recognition zone and a counting zone; a face recognition module, monitoring the recognition zone to determine a face location corresponding to a face through analyzing the recognition zone; a head recognition module, monitoring the counting zone to determine a head location corresponding to a head through analyzing the counting zone; an object tracking module, the head recognition module, generating a face track and a head track; and a people counting module, counting a first number of face tracks and a second number of head tracks passing through the counting zone and generating a counting result.

People counting system and method

A portable electronic apparatus and an interactive human face login method are disclosed. The portable electronic apparatus comprises a face database, a user interface, an image capturing device, and a recognition circuit. The face database stores a plurality of facial expression feature information. The user interface randomly generates a plurality of facial expression indications used for guiding a user to sequentially show a plurality of facial expressions. The image capturing device captures the facial expressions to output a plurality of facial expression images. The recognition circuit receives a login request and determines whether the facial expressions are consistent with the facial expression indications according to the facial expression feature information and the facial expression images. The login request is allowed if the facial expressions are consistent with the facial expression indications.
