Abstract

The invention discloses a face tracking method, comprising the steps of: generating a face reference area by performing face detection on a current image frame in a video sequence; identifying the face in the image frame from the reference area by a deep learning method The location of the facial features; select the region of interest of the face according to the location of the facial features of the image frame as the reference area of ​​the next image frame; and repeat the above identification steps and selection steps to track the facial features of each image frame in the video sequence Location. The invention also discloses a corresponding face tracking device.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a face tracking method and device. Background technique [0002] In the existing face tracking technology, it is generally first to find out the face area in the first frame of the video through face detection, and then continuously calculate the features such as color, corner point or optical flow in the face area, and in the next frame The region where the features are found to match is used as the face region of the next frame, and so on...to achieve face tracking in the video. However, the above scheme is greatly affected by lighting, face angle, etc., the tracking effect is poor, and the tracking frame is unstable, which is prone to tracking failure. [0003] Another improved face tracking solution is to achieve tracking by online learning of features in the face area. Although it can improve the tracking effect, online learning will increase the computational comp...
