The technology includes three modules used successively:

• Face Detection module
• Face Indexing (coding and fast search of faces in database)
• Face Identification module

Modules are applied in series. The images of faces, captured in the current frame, are moving to indexing module which take off on output 5-10 faces from data base similar to the face under testing. Then Face Identification module is used for more detailed recognition faces from the set. This approach allows to implement principle "from coarse-to-fine" in recognition process and to work with images in the "near real time" mode.

Below three frames are presented. In every frame one can observe (from top to bottom):

• image under testing
• face detected and extracted from image
• a set of candidates from the database
• final face identification

Modules are shaped and officially registered in the form of SDK:

• IIT FDT SDK - IIT Face Detection and Tracing SDK
• IIT FR SDK - IIT Face Recognition SDK
• IIT FI SDK - IIT Face Indexing SDK
