Classification: CPC G  Y | IPC G

Claim 0:
1. An object tracking method performed by a computer device, the method comprising:
determining a kernelized correlation filter (KCF) algorithm parameter according to device information of the computer device;
initializing the KCF algorithm according to the KCF parameter;
extracting a first local feature of a target object in an initial target object region of a first image frame in a video stream;
tracking the target object in first subsequent image frames after the first image frame in the video stream by using the KCF algorithm; and
performing the following operations when the target object is lost in a second image frame in the first subsequent image frames during the tracking:
determining, according to the first local feature and in second subsequent image frames starting with the second image frame, a third image frame in which the target object reappears for the first time after the target object is lost during the tracking;
determining a location of a target object region in the third image frame including the target object; and
continuing to track the target object in image frames after the third image frame according to the location of the target object region in the third image frame.
