Le Floch, Maxime2026-03-092026-03-092026-03-09https://opara.zih.tu-dresden.de/handle/123456789/2119https://doi.org/10.25532/OPARA-1119The RARE-VISION test dataset consists of three previously unseen capsule endoscopy examinations acquired with the Navicam system at the University Hospital Carl Gustav Carus, Technical University of Dresden. The dataset is strictly separated from the development data, and ground-truth annotations are withheld for final evaluation. Each case is provided as a complete chronological video sequence at a resolution of 480 × 480 pixels, preserving the original temporal order without trimming or manual segmentation. The three videos contain: 44,878 frames 53,220 frames 62,927 frames The data reflect real-world clinical variability and the natural class imbalance of capsule endoscopy, where rare pathological findings occur sparsely within long sequences of normal mucosa. Annotations are defined as temporal events (start frame, end frame, label) corresponding to the 17 competition target classes. The label set includes anatomical regions and pathological findings only; no anatomical landmarks are annotated. The dataset is designed to evaluate robust rare-event detection, temporal consistency, and fully automatic inference on long sequential video streams. The videos are provided exclusively for scientific research within the scope of the ICPR 2026 RARE-VISION competition and must not be used for any commercial purposes. For detailed terms of use, please refer to the official competition report and documentation. This study was approved by the Ethics Committee of the University Hospital Carl Gustav Carus at the Technical University of Dresden on December 16, 2022 (Ethics ID: BO-EK-534122022), confirming adherence to the ethical principles of the Declaration of Helsinki. Due to the retrospective anonymization of the data and their collection during clinically indicated routine interventions, explicit consent was not required. This is additionally supported by the Ethics Committee’s approval, a consultation with the data privacy officer, and local law. Section 34, Paragraph 1 of the Saxon Hospital Act (SächsKHG) explicitly allows the collection and analysis of this type of data.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/2::22::205::205-15
