 ## Changelog
-- **2026-07-27**: Added complete [Croissant metadata](./croissant.json), including Responsible AI fields, and VGGT reprojection-error reports for the two real-world `MTMC_Tracking_2026` test scenes: [`Warehouse_026`](./MTMC_Tracking_2026/test/Warehouse_026/vggt_reprojection_error.txt) and [`Warehouse_027`](./MTMC_Tracking_2026/test/Warehouse_027/vggt_reprojection_error.txt).
 - **2026-06-04**: Released 2 real-world test scenes for `MTMC_Tracking_2026` — `Warehouse_026` (4 cameras) and `Warehouse_027` (7 cameras), provided as 1080p / 30 FPS video covering the first 60 seconds (1800 frames) of each scene — the labeled evaluation window — with 2025-format `calibration.json`. An offline HOTA evaluator that reproduces the official AICity MTMC metric is available in the [`spatialai-data-utils` evaluation tools](https://github.com/NVIDIA-AI-Blueprints/video-search-and-summarization/tree/develop/libs/analytics/spatialai-data-utils/tools/evaluation) (`evaluate_aicity_mtmc.py`).
 - **2026-05-15**: Released 3 synthetic test sets for `MTMC_Tracking_2026`. The remaining real-world test sets are scheduled for release at the end of May. The evaluation system for the 2026 AI City Challenge Track 1 has also been postponed to the end of May. In addition, the 2025 AI City Challenge Track 1 evaluation system has been temporarily disabled and will be re-opened after the conclusion of the 2026 AI City Challenge.
 - **2026-04-29**: Initial release of `MTMC_Tracking_2026` — 26 scenes, 342 cameras, 28.5 camera-hours of 1080p video, 11.1M 3D boxes / 33.2M 2D boxes, with depth maps; calibration and GT aligned to the 2025 schema. 6 scenes (`Warehouse_001`, `_003`, `_005`, `_007`, `_021`, `_024`) are **Cosmos Transfer 2.5 (CT2.5) augmented** re-renderings of their source scenes (same scene/cameras/calibration/depth/GT, augmented RGB).
