ABSTRACT
Two major questions concerning this chapter may be asked: What is a wavelet? Why is it interesting for solving signal processing problem? These are crucial remarks that a signal analyst would want to know. The answer to these questions may be summarized as: Wavelet representation is a versatile technique having many physical and mathematical insights with great potential applications to signal and image processing. In other words, wavelets can be viewed as a new basis for representing signals and images that can be used for signal analysis and image synthesis.
