Research on LOD Wvelet Model of Virtual Face

A fast Iifted symmetrical cubic B-spline wavelet transform scheme with C2 smooth is put forward in the paper for the first time,which meets the needs of face construction.Through the introduction of S-lift and W-lift operators.l filter and h fiIter are constructed based on the two-scale two-order vanish moment relation.A tensor-product fornlal two-dimensional mesh MRA subdivision and continuous Ievel of detail control scheme is also studied to reconstruct face mesh.And a typical virtuaI face is constructed.The error is also analyzed and the results show that by using this LOD control model.the compression ratio is high and the distortion of facial surface is very small.
