Claim 0:
1. A facial recognition method, said method comprising the steps of:
extracting a feature descriptor from a detected feature point of a detected face in an input image frame from a video/image capturing device; and
matching the extracted feature descriptor with at least one of a pre-stored facial image that is index-mapped using a constrained deformable part-based model (CDPBM) 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 index-mapped facial images that matched above a pre-defined threshold from the first round of matching.
