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 13):
The device according to  claim 11 , wherein the processing module comprises:\n a first processing unit, when the detection result indicates predefined targets other than the target exist in the tracking ROI, for reinitializing the primary forecasting model and the verification model based on the predefined targets; a second processing unit, when the detection result indicates no predefined targets other than the target exists in the tracking ROI and the target tracking in the current frame was unsuccessful, for cancelling reinitializing the primary forecasting model and the verification model based on the predefined targets; and a third processing unit, when the detection result indicates no predefined targets other than the target exists in the tracking ROI and the target tracking in the current frame was successful, for performing parameter correction on the primary forecasting model and the verification model.
