wrong downscale method #31

Closed senpai-a closed 5 years ago

senpai-a commented 5 years ago

in train.py: comment says # Downscale (bicubic interpolation) but according to skimage documentation skimage.transform.resize is using order=1 by default which is bilinear(see warp )

i tried cv2.resize instead of scipy.interp cv2.resize reaches a psnr performance of 35+dB which is normal. though scipy.interp can only reach 33+dB (current implementation) i think there is a problem here.
