Abstract

An error resilient coding method for 3D graphic models is proposed in this research, which exploits the topology and geometry information of the original mesh to convert the mesh to a pre- defined 3D structure via morphing, and then partitions the morphed structure into a set of smaller pieces via volume splitting. By using the morphing and splitting processes, the error propagation length is greatly reduced since it is confined to each individual piece rather than the whole mesh. Different pieces are connected via their joint boundaries. By coding the joint boundaries separately, individual pieces can be reconstructed independently of each other. Consequently, error resilient coding can be conveniently applied to each piece. The number of pieces of partitioning is determined by channel error rates. It is demonstrated that the proposed method can achieve satisfactory results in an environment of bit error rates less than 10^-3.
