Data Compression with Hybrid Supercompact Wavelets
Do‐Hyung Lee, Hyungmin Kang, Dong-Ho Lee · 16th AIAA Computational Fluid Dynamics Conference · 2003
Data compression technique is proposed that co mbines 3D, 2D and 1D versions of supercompact. Computation domain is divided into subsets for each dimensional version of multiresolution appl icatio n. Compared to Harten's interpolatory mu ltiresolution, supercompact wavelets require small number of support points, lea d- ing to quite simple and less expensive numerical i m- plementation. The hybrid multiresolution method a l- lows high actual data compression for fluid simulation data since the method is based on highly effective wavelets and subdivision methods. Several numerical tests substantiate large data co mpression ratios for flow field simul ation.
