Reported quantities

Role	Count	Unit	Scope	Basis	Evidence
Primary	5,581	annotated_images	Current Dataset 1 v2 plus Dataset 2	derived_from_reported_components	ftp.itec.aau.at/datasets
Additional	843	annotated_images	Dataset 1 v2, manually annotated Cataract-101 frames	official_source_description	ftp.itec.aau.at/datasets
Additional	4,738	annotated_images	Dataset 2, CaDIS-derived annotations	official_source_description	ftp.itec.aau.at/datasets

Counts retain their source-reported units. Additional rows can describe components, paired items, or derivative copies and are not automatically added to the primary quantity.

Documented relationships

These links record source-supported lineage or overlap, not merely similar modality tags.

• This record is derived from cadis: InSegCat Dataset 2 converts CaDIS semantic masks to instance masks and boxes. (evidence)
• This record is derived from cataract_101: InSegCat Dataset 1 selects and annotates frames from Cataract-101 videos. (evidence)

Access information and download

CLI

# Read-only preflight
eyehub download insegcat --data-dir ./data --dry-run --json

# Download, only when preflight reports supported behavior
eyehub download insegcat --data-dir ./data

Python

from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY

ds = REGISTRY.get_dataset('insegcat')
print(preflight_dataset(ds, './data'))  # no download
