ABSTRACT

In this chapter we explore some additional topics that extend the basic ideas of wavelet analysis. We first describe wavelet packet transforms, which sometimes provide superior performance beyond that provided by wavelet transforms. Then we discuss continuous wavelet transforms which are particularly useful for tackling problems in signal recognition, and for performing finely detailed examinations of the structure of signals-we shall look at examples from ECGs, speech, and music. In the Notes and References section we provide a guide to the literature for more topics which, for reasons of space, we could not discuss.
