Wavelet-based multiresolution representing for 3-dimensional irregular data field
Jiaoying Shi · 1999
A new algorithm of the wavelet-based multiresolution representation for 3-dimensional irregular data field is presented. The volume wavelet functions as well as the corresponding analysis and synthesis filters, which can split the data field into a lower resolution part and a sequence of details, are constructed without changing the topology of object. It is available for a restricted class of data field with subdivision connectivity. And a new method for converting the completely arbitrary data field into multiresolution form is presented so that multiresolution representation can be applied to arbitrary data field.
