afterwards are merged together to an image again with the precomputed indices. img np.sum patchesWithColFlat ind axis 2 As patches.. it is necessary at the end to multiply the img with the precomputed weights imgOut weights imgOut My code is really slow and speed.. get_indices_for_un_patchify and weights_unpatchify can be precomputed once so speed is only an issue for patchify and unpatchify...
