Performance analysis of multiwavelets constructed using B-spline refinable super functions

Image compression performance of new multiwavelets constructed using B-spline super functions is compared with existing multiwavelets. First orthogonal, approximation order preserving pre-filters are designed and then an extensive comparative performance analysis in image compression is carried out. Our results confirm the usefulness of the super function design criteria in image compression. The new multiwavelets show excellent performance, which is better than most of the well known multi-wavelets and at least as good as the 9/7 biorthogonal wavelet.
