PWCC: Pixel-wise Color Constancy via Smoothing Techniques in Multi-Illuminant Scenes

---

This repository includes the implementation details of Pixel-wise Color Constancy (PWCC) proposed in arXiV:

Pixel-wise Color Constancy via Smoothing Techniques in Multi-Illuminant Scenes

PWCC learns a pixel-wise mapping, referred to as an illuminant map, between input and ground truth images. This mapping provides a white-balancing operation to the input image so that color casts can be minimized.

Conda environment setup:

# In Linux Environment:
$ while read requirement; do conda install --yes $requirement || pip install $requirement; done < envcc.txt
