Continuous Wavelet Transform
Wavelet transform is a mathematical tool that converts a signal into a different form. This conversion has the goal to reveal the characteristics or “features” hidden within the original signal and represent the original signal more succinctly. A base wavelet is needed in order to realize the wavelet transform. The wavelet is a small wave that has an oscillating wavelike characteristic and has its energy concentrated in time. Figure 3.1 illustrates a wave (sinusoidal) and a wavelet (Daubechies 4 wavelet) (Daubechies 1992).
