Claim 4:
5. The method of claim 1, wherein, at the step of (b), the object tracking device (i) crops the areas corresponding to the 1-st bounding boxes on the (1_1)-st specific pyramid feature map corresponding to a 1-st specific scale among the (1_1)-st pyramid feature map to the (1_k)-st pyramid feature map, wherein the areas are cropped by using resized 1-st bounding boxes with (1_1)-st widths and (1_1)-st heights and wherein the (1_1)-st widths and the (1_1)-st heights are acquired by multiplying (1) a ratio of the (1_1)-st specific pyramid feature map corresponding to the 1-st specific scale and the t-th frame (2) to 1-st widths and 1-st heights of the 1-st bounding boxes, such that the 1-st bounding boxes correspond to the 1-st specific scale, and (ii) generate the (1_1)-st cropped feature map by resizing the (1_1)-st widths and the (1_1)-st heights such that the (1_1)-st cropped feature map is larger than the 1-st bounding boxes and has a ratio of width to height that is same as the 1-st bounding boxes.
