CT images were utilized to construct 3D surface models, followed by an analysis of their surface curvature distribution. A statistical shape model (SSM) was created as a deformable mean model to identify the 6 landmarks. These landmarks were automatically identified in each patient model by registering the SSM in the individual patient models. Two registration methods were employed: the proposed curvature-based and previously established methods. Both methods involved rigid and nonrigid registration processes; however, the proposed method included additional curvature-based registration using a curvature-driven, nonrigid iterative closest point (ICP) algorithm. The Euclidean distances between the manually and automatically identified landmarks were measured and compared between the 2 methods.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The Euclidean distance was significantly lower in the gonion and right coronoid process when the proposed method was used compared to the previous method.
