Fig 1.
Sample normal and OA hip X-ray images.
The images have a pixel resolution of 0.187 mm x 0.187 mm, and were zoomed in on the osteophytes to highlight the differences between normal and OA patients. Left: Normal hip joint X-ray image. Right: OA image. The triangles indicate osteophytes of the acetabular rim bone. The arrows indicate the osteophytes of the greater trochanters of femurs.

They are: 1) the five images(①②③④⑤) in top row, the arthritic areas are located in the left hip joint; 2) the left three images(⑥⑦⑧) in bottom row, the arthritic areas are located in the right hip joint; 3) the right two images(⑨⑩) in bottom row, the arthritic areas are located in both hip joints.
