In conventional wavelet transforms, prefiltering is not necessary due to the lowpass property of a scaling function. This is no longer true for multiwavelet transforms. A novel adaptive multiwavelet prefilter is presented which is designed to overcome this problem. Simulation results show that the approximation accuracy of the prefiltering algorithm is satisfactory.
