Preprocessing for EyeSea

• Preprocessing experiments and applicators for EyeSea.
• Numerically optimized matrix computation implementation of image enhancement and color restoration algorithms.
• Callable image enhancement and restoration APIs.

Procedure to Execute

• Place the input images in data/input/ directory of the corresponding processing operation (i.e Color Restoration or Enhancement).
• Edit the corresponding run.py script to uncomment the algorithm to be applied.
• Execute the script:
  • To only generate the images: python run.py.
  • To visualize before-after stages for each image: python run.py --visualize.
• The processed images are stored in the corresponding data/output/ directory.
