Abstract: A method of managing visiting guests by face recognition includes: extract the face image of the visiting guest; determine if the face image of the guest is stored in the database; display the face image data comprising the face image, guest information and visiting information if the face image is stored or enroll the new face image data and then display the face image data just registered; set up at least one authorized item; execute the visiting goal confined by the authorized items; monitor the status of the visiting guest; wait until the guest leaves; and finally record and update log page and face image data of the visiting guest in the database. Therefore, the method can reduce security guard workload, assist security guards or automatically and solely execute the function of guard entrance without any careless mistakes, and update visiting guest information in real time.

Abstract: A method of surveillance by face recognition is disclosed. The method includes the steps of: first building up the face recognition database library in a storage medium comprising a plurality of face images; taking dynamic videos via an image capture device and showing the dynamic videos in the display device; performing face recognition to find the target face image in each dynamic video, and then determine the target face image as the matched or mismatched face image by comparing the target face image with the face images in the face recognition database library; and finally marking the matched and mismatched face images by different colored frames, respectively. Therefore, the method of the present invention can dynamically mark the target face images by images, colored frames and/or text to provide a solution of surveillance with high safety and efficiency.
