# Upstream provenance

Dataset recordings and calibration derive from the KITTI Vision Benchmark
Suite (Geiger et al., CVPR 2012 / IJRR 2013). The metadata is distributed under
CC BY-NC-SA 3.0. The self-contained Hub release includes original images and
point clouds under these same terms; the optional lightweight archive omits
sensor payloads. See LICENSE-DATA.

The optional model package is based on the UniCal reimplementation at
https://github.com/mcocheteux/unical-plus, whose declared license is CC BY-NC 4.0.
Its training initialized the encoder from `apple/mobilevit-small`, originally
released by Sachin Mehta and Mohammad Rastegari (MobileViT, ICLR 2022) and
pretrained on ImageNet-1k. The Hugging Face card specifies the Apple sample code
license, not Apache-2.0:
https://huggingface.co/apple/mobilevit-small

The upstream Apple license is retained as APPLE-MOBILEVIT-LICENSE.txt in the
baseline package (release/v1/APPLE-MOBILEVIT-LICENSE.txt in the metadata/source
package). Source:
https://raw.githubusercontent.com/apple/ml-cvnets/main/LICENSE
Retrieved 2026-10-17. Attribution and notices are preserved; the baseline
package's CC BY-NC 4.0 notice does not replace upstream subcomponent terms.
Neither Apple nor KITTI endorses this release.

The mirrored UniCal assessment (`docs/ASSESSMENT.md` and
`release/v1/assessment_results.json`) comes from unical-plus commit
2550c6dbab40d48f64bc260f03bf5e69d5bc5452 and retains its CC BY-NC 4.0 terms.
That license is included at release/v1/UNICAL-LICENSE.txt in the metadata/source
package and as LICENSE in the separate baseline package. The MIT code license
does not replace these assessment or upstream component licenses.

The v1.1 migration evaluation under `release/v1.1.0/baseline_evaluation/`
uses those unchanged UniCal checkpoints and retains CC BY-NC 4.0 for the
evaluation records. Their hashes identify the original model artifacts.
Original KITTI calibration text files and derived reference matrices under
`release/v1.1.0/` retain KITTI's CC BY-NC-SA 3.0 terms.
