1. Before going further, change your working directory to somewhere desirable place.

Below commands will make './WideGamutDataset', './WideGamutDataset/srgb-8bpc', './WideGamutDataset/prop-8bpc', and './WideGamutDataset/split' directories.

Then the corresponding contents will be downloaded into matching directories.

2. Downloading input images (sRGB)

wget -c --http-user=anonymous --http-password=anonymous -i WideGamutDataset_srgb-8bpc.txt -P ./WideGamutDataset/srgb-8bpc

3. Downloading target images (ProPhoto RGB)

wget -c --http-user=anonymous --http-password=anonymous -i WideGamutDataset_prop-8bpc.txt -P ./WideGamutDataset/prop-8bpc

4. Downloading split information.

wget -c --http-user=anonymous --http-password=anonymous -i WideGamutDataset_split.txt -P ./WideGamutDataset/split

After downloading split information, please replace paths in each file correctly. For example, change the content from

# Original 'WideGamutDataset/split/train-input.txt'
Z:\WideGamutDataset\srgb-8bpc\standard-nuscc-OlympusEPL6_0142.png
Z:\WideGamutDataset\srgb-8bpc\vivid-fivek-a1616-_DGW6356.png
Z:\WideGamutDataset\srgb-8bpc\standard-fivek-a1281-tc_DSC2356.png
...

to as follows:

# Updated 'WideGamutDataset/split/train-input.txt'
<to_correct_directory>\WideGamutDataset\srgb-8bpc\standard-nuscc-OlympusEPL6_0142.png
<to_correct_directory>\WideGamutDataset\srgb-8bpc\vivid-fivek-a1616-_DGW6356.png
