In this chapter, we introduce the concept of wavelets and describe how to use wavelet-based decompositions in compression schemes. We begin with an introduction to wavelets and multiresolution analysis and then describe how we can implement a wavelet decomposition using filters. We then examine the implementations of several wavelet-based compression schemes.
15.2 Introduction
In the previous two chapters, we looked at a number of ways to decompose a signal. In this chapter, we look at another approach to decompose a signal that has become increasingly popular: the use of wavelets. Wavelets are being used in a number of different applications.
