ImageNet-64 (True ILSVRC2012 Labels, Anti-Aliased 64×64 Center Crop)

Built directly from ILSVRC/imagenet-1k preserving the exact original label (0..999) and ClassLabel metadata for all:

Validation: 50,000 images (data/validation-00000-of-00002.parquet .. 00001)
Train: 1,281,167 images (data/train-00000-of-00030.parquet .. 00029)

Preprocessing (ADM / DiT `center_crop_arr(64)`)

Iterative $2\times$ Image.BOX downsampling while $\min(W, H) \ge 128$ to prevent aliasing.
Image.LANCZOS resize so $\min(W, H) = 64$.
Exact $64 \times 64$ center crop encoded as lossless RGB PNG.
