To person face, kind inside change often is more than kind a change, make be in thereby suffer kind inside use below the condition that change violates kind a change is divisional and individual become unusually difficult.

Person face identifies basically use at identity identifying. Because video monitoring is gaining ground quickly, numerous video monitoring application is pressing the fast capacity that needs blame of a kind of remote, user to cooperate condition to fall identifies a technology, in an attempt to is remote confirm personnel identity quickly, realize intelligent early-warning. Person face identifies a technology is very good choice undoubtedly, use fast person face to detect the technology can search person face in real time from inside monitoring video image, undertake be comparinged in real time is opposite with person face database, realize sudden status to identify thereby.
