Kind Code:
A1
Abstract:
A facial tracking method, an apparatus, a storage medium and an electronic device. Said method comprises: acquiring facial feature information of a current image frame in sequential images and facial tracking information of a previous image frame in the sequential images (S302), wherein the previous image frame is an image frame located before the current image frame in the sequential images, and information of a facial feature in the current image frame is recorded in the facial feature information, while the facial tracking information is used for recording a facial tracking result of the previous image frame; selecting an adjustment image frame from the previous image frame on the basis of the facial feature information of the current image frame and the facial tracking information of the previous image frame (S304); using facial tracking information of the adjustment image frame and the facial feature information of the current image frame to match adjustment parameters of the current image frame (S305); determining facial tracking information of the current image frame on the basis of the adjustment parameters and the facial tracking information of the previous image frame (S306). The technical problem wherein a high level of accuracy and low complexity are difficult to guarantee by using existing face registration point tracking algorithms is thus solved.
