datasets

1. PolyU Pure Color dataset

2. Single-illuminant dataset: Cube+ dataset

Cube+ is large enough to test DNN-based models and I have re-processed it into tiff and json format.

3. Pixel-wise dataset: LSMI dataset

I have re-processed the original LSMI dataset to facilitate faster model checking. However, the dataset remains quite large, approximately 30GB in total.
