ABSTRACT
When 3D objects occlude each other or self-occlude, their drawings typically consist of a set of contours that might partially overlap or self-overlap. The authors' method infers the hidden parts of contours and creates a smooth 3D shape matching those contours by solving a set of optimization problems.
INDEX TERMS
