1. A method for finding a temporal face sequence, the method comprising: applying, by a computing system, a face detection function to a shot within a video, wherein the shot comprises a series of frames; determining, by the computing system, a face detection instant, wherein the face detection instant is an instant the face detection function detects a face of a person within one frame of the frames; determining, by the computer system, a time the person enters the shot by backward tracking the person through the frames from the face detection instant; determining, by the computer system, a time the person leaves the shot by forward tracking the person through the frames from the face detection instant; determining, by the computing system, a time range from the time the person enters the shot to the time the person leaves the shot; and identifying a face temporal sequence for the person, wherein the face temporal sequence comprises the determined time range.
