Frictionless access control system embodying satellite cameras for facial recognition

A method for controlling access to an access control system, comprising:

• capturing image data by one or more surveillance cameras at an access point;
• extracting facial patches from the image data;
• ranking the facial patches above a predefined threshold by comparing a plurality of machine learning trained image quality factors to a plurality of detected features of a candidate facial patch of the facial patches to determine acceptable facial patches for individuals;
• computing facial signatures from the acceptable facial patches;
• matching the facial signatures to stored facial signatures;
• and
• using user identity information of individuals corresponding to the stored facial signatures when the facial signatures match the stored facial signatures.

A non-transitory computer-readable medium having instructions thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• capturing image data by one or more surveillance cameras at an access point;
• extracting facial patches from the image data;
• ranking the facial patches above a predefined threshold by comparing a plurality of machine learning trained image quality factors to a plurality of detected features of a candidate facial patch of the facial patches to determine acceptable facial patches for individuals;
• computing facial signatures from the acceptable facial patches;
• matching the facial signatures to stored facial signatures;
• and
• using user identity information of individuals corresponding to the stored facial signatures when the facial signatures match the stored facial signatures.
