# NICDF Aquatic Multi-Object Tracking Dataset (AquaTrack)

Release: `NICDF-v1.0.0`  
Institutional owner: **National Innovation Center for Digital Fishery (NICDF)**  
Public scope: **train only**

## Overview

A train-only aquatic multi-object tracking dataset released by NICDF, with sequence-safe frame metadata, COCO annotations, MOTChallenge views where identity annotations are available, and stable NICDF_taxon_id labels.

This repository is the reviewed ModelScope delivery view for `AquaTrack`. It contains training data only; validation, public-test, private-test, and evaluator-only material are not included.

## Dataset scale

- Training media records: 62,401
- Unique `asset_id` values: 62,401
- Unique media paths: 62,401
- Formal species identity: `NICDF_taxon_id` for one species or `NICDF_taxon_ids` for mixed-species records

The COCO view covers 62,401 images and 535,127 annotations. 35 complete sequences provide MOTChallenge identity annotations. Filter `tracking_annotation_available == true` for genuine MOT data; rows with `annotation_task_scope == detection_only` contain detection boxes but no track IDs. For RLE segmentations, `area` is the foreground-pixel count; otherwise it is bounding-box area.

## Repository layout

```text
.
|-- README.md
|-- LICENSE
|-- RELEASE.json
|-- data/train.csv
|-- media/sha256/...
|-- annotations/AquaTrack/...

|-- checksums.sha256
`-- checksums.modelscope.sha256
```

Each row in `data/train.csv` represents one training media asset. Core fields are:

- `asset_id`
- `image`
- `sha256`
- `file_size_bytes`
- `media_type`
- `modality`
- `width`
- `height`
- `source_dataset`
- `source_partition`
- `session_id`
- `sequence_id`
- `frame_index`
- `global_split`
- `split_basis`
- `annotation_set`
- `NICDF_taxon_id`
- `NICDF_taxon_ids`
- `taxon_count`
- `taxonomy_status`
- `canonical_name_zh`
- `scientific_name`
- `taxonomic_rank`
- `label`
- `label_name`
- `rights_status`
- `rights_id`
- `data_license`
- `institutional_owner`
- `publication_visibility`
- `tracking_annotation_available`
- `annotation_task_scope`
- `detection_annotation_available`
- `annotation_complete`
- `training_eligible`
- `mot_sequence`
- `mot_annotation_count`
- `mot_registry`
- `track_states_table`
- `coco_annotations`

`image` is a repository-relative path. Missing contextual fields are left empty and are not inferred. Site, batch, pond/tank, and date are not ModelScope-required fields.

## Loading

```python
from modelscope.msdatasets import MsDataset

dataset = MsDataset.load(
    "NICDFcau/NICDF-AquaTrack",
    subset_name="default",
    split="train",
)
```

The COCO, semantic-mask, and MOTChallenge files under `annotations/` are the authoritative task views. The platform table preview does not replace task-format parsing.

## Split and leakage policy

This repository exposes only `default/train`. NICDF validation and test partitions remain in the private evaluation chain and are not uploaded. Complete site, batch, session, event, and sequence groups are kept together.

## Taxonomy

Published records use reviewed `NICDF_taxon_id` values and include canonical Chinese names, scientific names, and taxonomic ranks. Koi cultivars and common carp share the species-level identity `Cyprinus carpio`; cultivar information remains in label views and is not presented as a separate species.

## Ownership and licence

- Institutional owner: National Innovation Center for Digital Fishery (NICDF)
- Data licence: CC BY-NC 4.0
- Redistribution scope: train-only release

Use of this dataset must comply with `LICENSE`.

## Citation

Until a related paper or DOI is issued, cite the institutional dataset record:

## Known limitations

- Only training data are provided; test labels are not public.
- Sessions with verified source annotation gaps and one complete sequence affected by a ModelScope delivery block were excluded and are listed in `metadata/release_exclusions.csv`.
- Image quality, viewpoint, density, and occlusion vary across sources.
- The same canonical media asset may be reused across NICDF task datasets through a stable `asset_id` and SHA-256.

## Integrity

`checksums.sha256` records the canonical NICDF source bytes before upload. ModelScope may normalize
line endings in text files such as XML and Markdown. For a repository downloaded from ModelScope,
verify against `checksums.modelscope.sha256`, which records the platform-delivered bytes and covers
all release files except itself and the platform-maintained `dataset_infos.json`. Both manifests are
provided so that source provenance and downloadable-byte reproducibility remain independently auditable.
