Classification: CPC G | IPC G

Claim 11:
12. The object tracking device of claim 9, wherein, at the process of (II), the processor (i) adds (1) leveled feature maps acquired by converting each of the (1_1)-st cropped feature map and the (2_1)-st specific pyramid feature map into each one-dimension vector, and (2) a position conversion map acquired by changing (x, y) coordinates which are positional information of features of the (1_1)-st cropped feature map and the (2_1)-st specific pyramid feature map into Random Fourier Features each of which is each sum of a cosine function and a sine function, and performs operations related to self-attention on a summation of said (1) and said (2), to thereby generate a 1-st self-attention result and a 2-nd self-attention result respectively corresponding to the (1_1)-st cropped feature map and the (2_1)-st specific pyramid feature map, and (ii) generates the (1_1)-st conversion feature map and the (2_1)-st conversion feature map by performing operations related to cross-attention on the 1-st self-attention result and the 2-nd self-attention result.
