prepro apply_transform interpolation uses order=0 (nearest neighbour) resulting in images with artifacts #181

Default for scipy.ndimage.interpolation is order=3 which results in smooth images. Using order=0 in tensorlayer apply_transform function results in images with artefacts.

Suggest to change to order=3

Order = 0

order0

Order = 3

order3
