Abstract

The embodiments of the present invention disclose a face tracking method and device. According to one specific embodiment of the invention, the method includes the following steps that: the location information of a target face object in a previous image frame of a current image frame in a video sequence is acquired, and the image information of a region where the target face object is located isextracted from the previous image frame of the current image frame, wherein the image information of the region is indicated by the location information of the target face object, so that a target face image corresponding to the previous image frame can be formed; the search region of the target face object is determined from the current image frame according to the location information of the target face object in the previous image frame of the current image frame, and the image information of the search region is extracted, so that a search region image corresponding to the current image frame can be formed; and the target face image corresponding to the previous image frame and the search region image corresponding to the current image frame are inputted into a face region positioningmodel, and the location information of the target face object in the search region can be outputted. With the embodiments of the invention adopted, face tracking accuracy can be improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically to the field of image processing technology, and in particular to a face tracking method and device. Background technique [0002] With the development of computer technology, image processing technology has been applied to more and more fields. Among them, the face tracking technology based on image sequences is a technology that detects faces from videos and captures information such as the position and size of faces in subsequent frames. [0003] In face tracking technology, traditional methods include model-based tracking and motion information-based tracking. Among them, model-based tracking is to obtain the prior knowledge of the target, establish a model based on skin color, relative position of facial features, etc., and match each frame of image through a sliding window. Tracking based on motion information is to use the continuity law of targ...
