when i read the code, i am confused about th13 = (2 * xc - input_W - 1) / (input_W - 1), cloud you give some links for explain this code. thanks.

Hi, it Is just affine transformation plus conversion of coordinate system (from pixel space to normalized space used by bilinear transfom in torch.

try Google - affine transformation . (or pytorch spatial transformer tutorial)
