An efficient error protection scheme for point based 3-D models over packet erasure network

In this paper, an efficient error protection scheme for the transmission of point based 3D model over packet erasure network is described. This scheme deals with the limitation in conventional 3D mesh model transmission where the quality of the reconstructed model is highly dependent on the lossless transmission of 3D connectivity information and the correct decoding of lower hierarchical layers of the Level of details (LOD) mesh for progressive reconstruction. The proposed scheme is particular well designed to provide connectivity and layer dependency free transmission of the static 3D model across network. Coupled with error protection technique for resilience towards packet loss during transmission, the proposed algorithm is effective in ensuring the graceful degradation of the decoded model both visually and objectively as shown from the experimental results.
