An important topic in computer vision is 3D object reconstruction from line drawings. Previous algorithms either deal with simple general objects or are limited to only manifolds (a subset of solids). In this paper, we propose a novel approach to 3D reconstruction of complex general objects, including manifolds, non-manifold solids, and non-solids. Through developing some 3D object properties, we use the degree of freedom of objects to decompose a complex line drawing into multiple simpler linedoi:10.1109/iccv.2013.181 dblp:conf/iccv/YangLT13 fatcat:vypzr6ov6jhwpb2zcj3jsmd6le
