Application ID: 14339469

Base Claim:
1. A face annotation method adapted for a current owner to annotate contacts in online social networks (OSNs), the face annotation method comprising: providing a pyramid database access control (PDAC) module which consists of a plurality of pyramid database units and performs a first batch of access control procedure and a non-first batch of access control procedure, wherein the pyramid database unit includes a plurality layers of database and is constructed according to social relationship information; providing a multiple-kernel learning face recognition (MKL-FR) module of the current owner implemented through the use of a MKL classifier unit which uses a MKL algorithm to achieve a face identification, wherein the MKL classifier unit is trained with the pyramid database unit accessed in OSNs and includes an offline learning procedure and an online recognition procedure; and if the MKL-FR model is not able to identify query faces, providing a multiple-kernel learning face recognition fusion (FRF) module to perform a collaborative face recognition strategy by utilizing a user who features a highest priority rule within a collaborative face recognition framework based on characteristics of OSNs.

Claim 7:
7. The face annotation method as recited in claim 1 , wherein the first batch of access control procedure further includes: a match set of all face images belonging to the identity label subset corresponding to a temporal context of the pyramid database unit is first accessed and forwarded to the MKL classifier unit of the current owner for the face identification; after the results of the face identification are returned, if a score vector exceeds a class threshold, an first access control is labelled with 1, which indicates that the identity of corresponding query face images needs to be annotated as recognized; and otherwise, the first access control is labelled with 0, which indicates that the first batch of access control procedure has to provide the MKL classifier unit of the current owner with the match set of face images of the next layer identity label subset that has been constructed to identify query faces again.
