Digital Knee X-ray Images

The dataset consists of 1650 digital X-ray images of knee joint which are collected from well reputed hospitals and diagnostic centres. The X-ray images are acquired using PROTEC PRS 500E X-ray machine. Original images are 8-bit grayscale image. Each radiographic knee X-ray image is manually annotated /labelled as per Kellgren and Lawrence grades by 2 medical experts. A novel approach has been developed to automatically extract the Cartilage region (region of interest) based on density of pixels.
