Description
The Knee Osteoarthritis Dataset with Severity contains nearly 10,000 X-ray images of the knee, annotated according to the KL system (Kellgren-Lawrence) with 5 grades ranging from healthy to severe. This dataset is designed for the automatic detection and evaluation of the severity of osteoarthritis using computer vision methods.
What is this dataset for?
- Develop models to aid medical diagnosis in orthopedic imaging
- Classifying the severity of knee osteoarthritis on X-ray images
- Contribute to research in medical artificial intelligence and computer vision
Can it be enriched or improved?
This dataset can be enriched by additional annotations (precise location of the lesions, segmentations). It is also possible to add associated clinical data to improve predictive models.
