Claim Text:
1. A method of generating a personalized 3D avatar mesh of a human subject from a depth camera image for medical imaging scan planning, comprising: converting a depth camera image of a subject to a 3D point cloud; detecting a plurality of anatomical landmarks in the 3D point cloud; initializing a 3D avatar mesh by aligning a template mesh to the 3D point cloud based on the detected anatomical landmarks; and generating a personalized 3D avatar mesh of the subject by optimizing the 3D avatar mesh using a trained parametric deformable model (PDM) wherein generating a personalized 3D avatar mesh of the subject by optimizing the 3D avatar mesh using a trained parametric deformable model (PDM) comprises: optimizing parameters of the trained PDM that control a pose and shape of the 3D avatar mesh and locations of vertices of the 3D avatar mesh to minimize a cost function, and wherein the cost function includes a table constraint that causes the optimization to move vertices of the 3D avatar above a table on which the subject is lying.
