+# Dataset Card for HyperKvasir
+
+<!-- Provide a quick summary of the dataset. -->
+
+HyperKvasir is the largest publicly available dataset for gastrointestinal (GI) endoscopy, consisting of over 110,000 images and 374 videos, including labeled, unlabeled, and segmented samples. It supports tasks such as classification, segmentation, object detection, and anomaly detection in GI disease diagnostics.
+
+## Dataset Details
+
+### Dataset Description
+
+HyperKvasir is a comprehensive multi-class dataset collected from real gastro- and colonoscopy examinations at Bærum Hospital, Norway. It contains:
+- 10,662 labeled images across 23 classes
+- 99,417 unlabeled images
+- 1,000 polyp images with segmentation masks and bounding boxes
+- 374 endoscopy videos (11.62 hours)
+
+- **Curated by:** Simula Research Laboratory and Bærum Hospital, Norway
+- **Funded by [optional]:** Not specified
+- **Shared by [optional]:** Simula Research Laboratory
+- **Language(s) (NLP):** English (annotations and metadata)
+- **License:** Creative Commons Attribution 4.0 International (CC BY 4.0)
+
+### Dataset Sources [optional]

+
+## Uses
+
+### Direct Use
+
+- Development and benchmarking of computer vision models in medical imaging
+- Training models for GI tract disease detection
+- Medical education and training support
+- Polyp detection and segmentation research
+
+### Out-of-Scope Use
+
+- Direct clinical diagnosis or patient treatment decisions without expert review
+- Non-medical imaging tasks or commercial uses without adherence to license terms
+
+## Dataset Structure
+
+- **Labeled Images:** 10,662 images in 23 diagnostic and anatomical classes
+- **Unlabeled Images:** 99,417 unannotated GI endoscopy images
+- **Segmented Images:** 1,000 polyp images with corresponding masks (JPEG) and bounding boxes (JSON)
+- **Videos:** 374 AVI format videos with frame-level annotations in 171 sequences
+
+## Dataset Creation
+
+### Curation Rationale
+
+Created to fill the lack of large, diverse, and annotated GI endoscopy datasets for AI research, especially for deep learning-based detection and classification tasks.
+
+### Source Data
+
+#### Data Collection and Processing
+
+Collected from routine clinical examinations using standard endoscopy equipment. Data were de-identified and curated, with videos annotated by expert gastroenterologists.
+
+#### Who are the source data producers?
+
+Medical professionals from Bærum Hospital, Norway, including gastroenterologists and technical staff.
+
+### Annotations [optional]
+
+#### Annotation process
+
+Annotations were performed manually by trained gastroenterologists following clinical diagnosis protocols. Segmentations include bounding boxes and pixel-level masks for polyps.
+
+#### Who are the annotators?
+
+Experienced medical doctors and clinical experts in gastroenterology.
+
+#### Personal and Sensitive Information
+
+The dataset has been anonymized and de-identified to protect patient privacy. No personally identifiable information is included.
+
+## Bias, Risks, and Limitations
+
+- Collected from a single hospital, so geographical and device variation is limited.
+- Some categories may be underrepresented, leading to class imbalance.
+- Videos are annotated for only a subset of findings.
+
+### Recommendations
+
+Users should consider class imbalance and lack of multi-center data when generalizing model results. Medical models trained on this dataset should be validated on diverse clinical data.
