An Automatic Knee Osteoarthritis Diagnosis Method Based on Deep Learning: Data from the Osteoarthritis Initiative

Figure 1

Computer-aided OA diagnosis pipeline. The entire process consists of two stages, including knee segmentation and OA severity classification. Typically, the knee segmentation depends on human efforts or manually selected features. Then, a machine learning model, such as CNN, is trained to classify the knees based on the OA severity grades.
