# Complementary NTIRE Real images

This prefix contains 25,000 additional NTIRE `label=0` Real
images. Every image has `width > 512` and
`height > 512`. The original 12,607 rows remain in
seven immutable `train-xxxxx-of-00007.parquet` files; the 12,393
`shard_4` continuation is stored in seven
`train-append-shard4-xxxxx-of-00007.parquet` files.

The append selection excludes every `sample_id` or image SHA-256 already in
the 50K `NTIRE/real` set or the original Complementary set. Original JPEG bytes
are embedded without re-encoding and every row matches profile
`d39db51fdcf2ed8c0f2148e77eb00b5f48d4993e8fa2d5e501a28188e1fd9f44`.

```python
from datasets import load_dataset

dataset = load_dataset(
    "Edward0707/TechJam2026_Jamlai_Bench",
    data_files={"train": "Complementary/train-*.parquet"},
)
```

`selection_manifest.csv` contains row-level provenance and hashes;
`summary.json` records both immutable generations and their validation.
