NICDF Aquatic Object Detection and Segmentation Dataset (AquaDetSeg)

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

Overview

A train-only aquatic-object detection and segmentation dataset released by NICDF, providing COCO detection/instance annotations, semantic masks where available, and stable NICDF_taxon_id labels.

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

Dataset scale

  • Training media records: 12,818
  • Unique asset_id values: 12,818
  • Unique media paths: 12,818
  • Formal species identity: NICDF_taxon_id for one species or NICDF_taxon_ids for mixed-species records

The COCO view contains 12,659 images and 72,769 annotations. The semantic-mask table contains 221 unique masks. Every published semantic mask is a single-channel uint8 PNG with class indices 0 (background) and 1 (foreground). Antialiased grayscale crab masks were thresholded at >=128, and byte-identical duplicate source occurrences were represented once per asset.

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

  • semantic_masks_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 

from modelscope.msdatasets import MsDataset

dataset = MsDataset.load(
    "NICDFcau/NICDF-AquaDetSeg",
    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.

Known limitations

  • Only training data are provided; test labels are not public.
  • Semantic masks are available only for the subset identified by has_semantic_mask.
  • 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.
