Specifically, this is the `images1024x1024` set - faces are aligned and cropped to 1024x1024. Original PNG files were transcoded to WEBP losslessly to save space and packed to WebDataset format for ease of streaming. The original filenames are kept (with different file extension) so that you can match against external attributes (e.g. text caption, facial landmarks). Each WebDataset shard corresponds to an original folder, containing 1,000 of pre-shuffled images. There are 70 shards in total, equivalent to 70,000 images. |
