Abstract: The aim of the paper is to investigate a novel lifting wavelet algorithm based on a Gaussian prediction operator to filter freeform surfaces represented by 3D triangular meshes. The proposed algorithm is based upon the lifting scheme where wavelet decomposition is implemented using three major operators; the split, predict and update operator. This paper proposes a novel prediction operator based on a Gaussian function. The proposed algorithm is used to filter computer generated and real freeform surfaces and the results are compared with another lifting wavelet algorithm based on mesh relaxation prediction. Comparison shows that a Gaussian prediction operator achieved smoother results for the same decomposition levels.
