Data Pre-processing for SelfDZSR

A demo for data pre-processing of short-focus image and telephoto image.

1. Crop short-focus image

  • Given the short-focus image ./short-focus.JPG and telephoto image ./telephoto.JPG, we first crop the short-focus image based on the focal-length ratio between the two images.

    python crop_center.py

  • Then we can get ./short-focus_center.png, it has roughly the same scenes as the telephoto image.

2. Position alignment

  • We use PWC-Net to align ./short-focus_center.png and ./telephoto.JPG spatially.

    python pwc_net.py

  • Then we can get the aligned telephoto image, named ./position_alignment/HR_warp.png.

3. Color alignment

  • Color alignment is performed between ./short-focus_center.png and ./position_alignment/HR_warp.png.

    python color_alignment.py

  • Finally, the low-resolution image ./color_alignment/LR.png, high-resolution image ./color_alignment/HR.png, and reference image ./color_alignment/Ref.png can be obtained.
