Abstract
A frictionless access control system and method embodying satellite cameras for facial recognition are disclosed. The cameras capture image data of individuals at an access point such as a door. Preferably, two or more cameras are placed on opposite sides of the access point to increase the likelihood that the individuals are captured in the image data. A facial cropper module extracts facial patches from the image data, and a facial signature module computes facial signatures from the facial patches. A facial recognition module receives the computed facial signatures from the facial signature module, matches the computed facial signatures to stored facial signatures, and sends user identity information of individuals corresponding to the stored facial signatures to the facial signature module when the computed facial signatures match the stored facial signatures.
