Deformable Human Body Modeling from 3D Medical Image Scans

Creating an accurate virtual human body model is challenging but required in many fields. This study presents a method to create 3D human body models from medical image scans. Visible light scanning of articulated 3D objects such as the human hand has limitation due to the self-occlusion of surfaces in certain poses. We present a complete system to create a deformable articulated human body volume from multiple 3D MRI scans of a living person, which can produce accurate volume deformation containing inner anatomical layers. The method combines technologies involving medical imaging, and computer vision, as well as computer graphics, to address the practical issues involved in producing detailed volume models from living human scans. The results provide an occlusion free person-specific 3D human body model, asymptotically accurate inner tissue deformations, and realistic volume animation of articulated movements driven by standard joint control estimated from the actual skeleton.
