Claim 14:
15. The object tracking device of claim 9, wherein, at the process of (II), the processor (i) generates the (1_1)-st conversion feature map and a (2_1)-st conversion feature map, wherein the (1_1)-st conversion feature map is acquired by converting each of the 1-st features of the 1-st cropped feature map to the 1-st feature descriptors containing the feature information and the location information of each of the 1-st features through performing operations related to self-attention and cross-attention on each of the (1_1)-st cropped feature map and the (2_1)-st specific pyramid feature map, wherein the (2_1)-st conversion feature map is acquired by converting each of the 2-nd features of the (2_1)-st specific pyramid feature map into the 2-nd feature descriptors containing the feature information and the location information of each of the 2-nd features, (ii) calculates each of the 1-st matching probabilities of each of descriptor pairs by matching each of the 1-st feature descriptors on the (1_1)-st conversion feature map and each of the 2-nd feature descriptors on the (2_1)-st conversion feature map, and (iii) acquires each of the 1-st matching pairs by using location information on specific 1-st feature descriptors and location information on specific 2-nd feature descriptors excluding outliers among specific descriptor pairs having the 1-st matching probabilities greater than the preset threshold.
