Raising Multiwavelet Approximation Order Through Lifting
Fritz Keinert · SIAM Journal on Mathematical Analysis · 2001
Given a pair of biorthogonal, compactly supported multiwavelets, we present an algorithm for raising their approximationorders to any desired level, using one lifting step and one dual lifting step. Free parameters in the algorithm are explicitly identified, and can be used to optimize the result with respect to other criteria.
