I have two Tensors A and B,
A.shape is (b,c,100,100),
B.shape is (b,c,80,80),
how can I get tensor C with shape (b,c,21,21) subject to
C[:, :, i, j] = torch.mean(A[:, :, i:i+80, j:j+80] - B)?
I wonder whether there’s an efficient way to solve this?
Thanks very much.
Sorry if it’s not a proper title.
