Abstract:
The present application belongs to the field of biometrics. Disclosed are a face tracking method and apparatus, and a storage medium and a device. The method comprises: performing facial detection on the current frame of image, so as to obtain the current face position in the current frame of image; obtaining the next face position in the next image by means of face tracking; calculating a similarity S1 between the face at the current face position and the face at the next face position, which is obtained by means of tracking, and when the similarity S1 is greater than a set first tracking threshold value, determining that face tracking is successful, otherwise, performing facial detection on the next frame of image, so as to obtain the next face position; calculating a similarity S2 between the face at the current face position and the face at the next face position, which is obtained by means of detection, and calculating a position overlap similarity between the current face position and the next face position, which is obtained by means of detection; and when the similarity S2 and the position overlap similarity are both greater than respective corresponding threshold values, determining that face tracking is successful.
