Hello authors, Thank you for sharing for us to learn from your excellent work. I have a stupid question about T^{i+1}j, equ(1b) in the paper. With equ(1a) we transform all the frames in a window into the first frame of the window to get F^{i+1}{j}. If we want to calculate T^20, i =1, j =0, s =3. With equ(1a) , we have the following result, how to understand this result. T^{i}{j,k} is the relative pose between T^i_j and T^i_k. image
