Feature enhancing based hole filling algorithm for 3D mesh model

A novel hole filling simplification algorithm based on feature-enhancing is proposed to improve the missing features reparation. First, the constraint points area of radial basis function is estimated to confirm the filling surface of hole area. And then, the hole surface is sampled and delaunayed according to the topological structure of the neighboring points. At last, the reparation features are enhanced to improve the detail feature of hole area. Experimental results show that the proposed algorithm is robust and effectively.
