Target tracking method, computer device, and storage medium

A computer device, comprising:

• at least one memory storing computer program instructions;
• and
• at least one processor coupled to the at least one memory and, when executing the computer program instructions, configured to perform:
• determining a target candidate region of a current image frame;
• capturing a target candidate image matching the target candidate region from the current image frame;
• determining a target key point position by using a target positioning model and according to an image feature of the target candidate image;
• determining a target region of the current image frame according to the target key point position;
• determining motion prediction data of a next image frame relative to the current image frame by using a motion prediction model and according to the image feature of the target candidate image;
• and
• determining a target candidate region of the next image frame according to the target region and the motion prediction data.

A non-transitory computer-readable storage medium storing computer program instructions executable by at least one processor to perform:

• determining a target candidate region of a current image frame;
• capturing a target candidate image matching the target candidate region from the current image frame;
• determining a target key point position by using a target positioning model and according to an image feature of the target candidate image;
• determining a target region of the current image frame according to the target key point position;
• determining motion prediction data of a next image frame relative to the current image frame by using a motion prediction model and according to the image feature of the target candidate image;
• and
• determining a target candidate region of the next image frame according to the target region and the motion prediction data.
