In this study, a 3-D semi-automated segmentation method of knee cartilages from MR images was proposed. The segmentation process is based on a graph-cuts algorithm and was evaluated with experiments on MR images from osteoarthritis initiative (OAI) database. It was significantly more efficient and reproducible than the manual delineation method.
