Claim 17:
18. A facial recognition system comprising:
a processor, a non-transitory storage element coupled to the processor, encoded instructions stored in the non-transitory storage element, wherein the encoded instructions when implemented by the processor, configure the system to:
receive a video and/or image from a surveillance or access-control point for parsing into image frames or segments;
extract a feature descriptor from a detected feature point of a detected face in the input image frame or segment; and
match the extracted feature descriptor with at least one of a pre-stored facial image using a constrained deformable part-based model (CDPM) that uses Histogram of Gradient (HoG) as part-based filters and trained by latent Support Vector Machine (SVM) to determine face feature point location and geometry, comprising at least a first and second round of matching, wherein the second round of matching only selects the facial images that matched above a pre-defined threshold from the first round of matching wherein the access control point further comprises at least one of the following provisioning: allow access to a venue/event, deny access to a venue/event, or process a purchasing transaction.
