hi, I notice that, in your 'batch_displacement_warp2d' method, you had assumed that the range of vector field (deformation field) is ranged in [0, xlen][0, ylen]. but I review the "VectorCNN" class, this sub-network may produce negative value. so could you please tell me why the vector field range must be [0, xlen][0, ylen] rather than [-xlen, xlen][-ylen, ylen]. thx.

Hi. It's a mistake I made while documenting. I've already fixed it. Thanks for pointing that out.
