# Representative subsets

The current `samples/` directory is a complete corruption/severity preview,
not a training or statistically representative evaluation split.

| Subset | Coverage | Selection | Files | Approx. size |
|---|---|---|---:|---:|
| KITTI-FC | 20 image/inter-frame corruptions x 5 levels + clean | pairs `000000`, `000171` | 404 PNG | 286 MB |
| GoPro-FC-10FPS | 24 corruptions x 5 levels + clean | frame pair `000096` from 5 sequences | 1,210 PNG | 1.4 GB |
| GoPro-FC-30FPS | 24 corruptions x 5 levels + clean | frame pair `000096` from 5 sequences | 1,210 PNG | 1.4 GB |

Total: 2,824 PNG files, approximately 3.1 GB (2.9 GB compressed).

GoPro-FC additionally includes `object_motion_blur`, `h264_crf`, `h264_abr`,
and `bit_error`. The five GoPro sequences are listed in
`splits/gopro_sequences.txt`.

## Quick preview

To keep the first inspection download small, the quick preview retains one
representative corruption from each category at levels 1, 3, and 5, plus clean
pairs: JPEG Compression, Over Exposure, Snow, Gaussian Noise, Object Motion
Blur, and H.264 CRF. It uses KITTI pair `000000` and GoPro pair `000096` from
`GOPR0374_11_02` at both sampling rates. Categories unavailable for KITTI-FC
are included only for GoPro-FC. This archive is for format and visual
inspection; benchmark scores must use the declared full test split.
