Question about coordinate in different stride

[ruanhao5]

Thanks for your great work. Could you please tell me how to calculate coordinate in different stride? code For example, I have got coord_s1 which shape is (batch, 3, height, width). How to calculate coord_s2 ?

Simply sample the 0, 2, 4, ... , 2n columns of coord_s1.
