Abstract:
The present disclosure provides a method and a device for target tracking. The method includes: obtaining a primary forecasting model and a verification model of a target, the primary forecasting model containing low-level features of the target and the verification model containing high-level features of the target; obtaining a current frame of a video image and determining a tracking region of interest (ROI) and a motion-confining region in the current frame based on a latest status of the target, wherein the tracking ROI moves in accordance to a movement of the target; forecasting a status of the target in the current frame in the tracking ROI based on the primary forecasting model; and determining a target image containing the target based on the status of the target in the current frame. The method further includes extracting high-level features of the target from the target image.

Claim (Index 16):
The device according to  claim 10 , wherein when the matching level between extracted high-level features and the verification model is greater than or equal to a predetermined similarity threshold value, and the current position of the target in the target image is outside the motion-confining region,\n the second obtaining module determines a tracking ROI of the target in a next frame based on the latest status of the target; and the first determining module determines whether the target tracking is successful in the next frame based on the tracking ROI in the next frame, the primary forecasting model, and the verification model, and when it is determined the target tracking is unsuccessful, and returns to determining a tracking ROI of the target in a next frame based on the latest status of the target to determine whether the target tracking is successful in the next frame.
