Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A target tracking apparatus comprising:
a memory configured to store a first image and a second image; and
a processor configured to:
obtain similarity information of a target in a target region in a first image and a searching region in a second image, including extracting feature information of the target in the target region in the first image;
obtain similarity information of a background in the target region and the searching region in the second image, including extracting feature information of the background in the target region and extracting feature information of the searching region in the second input image;
obtain a score matrix based on the obtained similarity information of the target and the searching region and the obtained similarity information of the background and the searching region; and

estimate a position of the target in the searching region from the score matrix, wherein the processor is further configured to:
obtain a first feature map from the target region;
obtain a second feature map from a region obtained by removing the background from the target region;
obtain a third feature map from a region obtained by removing the target from the target region; and
obtain a fourth feature map from the searching region.
