Visual hull of object has been widely applied in many fields in computer vision. The methods computing visual hulls are mainly classified into two categories: surface-based approaches and volume-based approaches. Surface-based approaches are precise and lack robustness while volume-based approaches are robust but inaccurate and work slowly. However, the speeds of both methods cannot satisfy the demand of real-time application. The paper proposes a novel method to compute visual hull rapidly. To this aim, the method is based on viewing lines. First, the viewing lines are computed from all the c...
