This is the ReLighting Surreal Intrinsic Dataset (RLSID), which is proposed in the paper "Image editing of light and color from a single image: a baseline framework"

The data is located in the ./data folder. The structure after unpacking is as follows:

├─Image: The original images.

├─Reflectance: The reflectance components of the original images.

└─Shading: The shading components of the original images.

The folder ./data_split contains a split version to assist users with poor internet connections. So, only one of them (./data and ./data_split) needs to be downloaded.

The image file in each folder is named aaa_bbb_xxx_yyy_zzz.png.

aaa: index of the scene

bbb: background information

xxx: pan

yyy: tilt

zzz: color

For the images from the same scene, aaa_bbb are identical while xxx_yyy_zzz determine the light conditions.

The "annotation" folder contains details about how the experiments in the paper divided the dataset.

train.txt: the training set.

val_pairs.txt: the validation set.

test_quantitative_pairs.txt: the testing set.

test_qualitative_pairs: some pairs randomly selected from the testing set for qualitative visualization.
