COMPLETION OF MULTIVARIATE WAVELETS
Ghanshyam Bhatt, Fritz Keinert · International Journal of Wavelets Multiresolution and Information Processing · 2007
The construction of wavelet functions from known scaling functions is called the 'completion problem'. Completion algorithms exist for univariate wavelets, including multiwavelets. For multivariate wavelets, however, completion is not always possible. We present a new algorithm (a generalization of a method of Lai) which works in many cases.
