Abstract This paper proposes an adaptive multiwavelet prefilter. The prefilter deals with the multi-wavelet initialization problem resulting from the non-lowpass property of multiscaling functions. Theory analysis and simulation results show that the approximation accuracy of the prefiltering algorithm is satisfactory.

Key words： Adaptive prefilter Multiwavelet transform Multiscaling function
