Title: METHOD AND DEVICE FOR TARGET TRACKING
Abstract:
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 extracted through a first descriptive method and the verification model containing high-level features of the target extracted through a second descriptive method, a complexity level of the first descriptive method is lower than a complexity level of the second descriptive method(S101); 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(S102); forecasting a status of the target in the current frame in the tracking ROI based on the primary forecasting model(S103); and determining a target image containing the target based on the status of the target in the current frame(S104). The method further includes extracting high-level features of the target from the target image.
