Abstract
A face detection method and apparatus and a security system employing the same. The face detection method includes: determining whether or not a face is detected in a previous frame image; if a face is not detected in the previous frame image, detecting a face in a first image according to one detection mode selected from N face detection modes, where N is an integer equal to or greater than 2; and if a face is detected in the previous frame image, detecting a face by performing sequentially at least one tracking mode of N face tracking modes with a second image.
