• Adjust hue, brightness, and contrast separately
• Duplicate images with adjustments applied to expand dataset

Required Packages:

• OpenCV
• numpy
• Pillow

How to use: python hue_adjustment.py -b -c -u -d 10

Before running the script, make sure to set the hr_dir, lr_dir, and output_hr_dir / output_lr_dir paths. Set these to your hr, lr, and output folders respectively.

There are adjustable range values in the script. Set these to the desired ranges. The defaults should be good enough
