Abstract
SPIHT is a very efficient image compression algorithm that is based on the idea of coding groups of wavelet coefficients as zerotrees. This method is well suited for the dyadic wavelet transform, where child-parent relations are easily established. In this paper we investigate how the SPIHT algorithm can be used for any arbitrary wavelet packet basis.
