Title
(EN) METHOD AND DEVICE FOR FACE TRACKING AND SMART TERMINAL
Abstract
(EN)

A method and device for face tracking and a smart terminal. The method includes: collecting a frame of an image in a video stream and conducting face detection and identification, to identify a target face; determining a position of a window to be tracked that contains the target face according to the identified target face, and extracting an edge feature point in the window to be tracked of the reference frame; determining an initial position of a window to be tracked on the current frame in the video stream, and extracting an edge feature point in the window to be tracked of the current frame; calculating a relative displacement between the edge feature point of the reference frame and the edge feature point of the current frame; and adjusting the initial position of the window to be tracked of the current frame by using the relative displacement.
