Relative Wavelet Energy

It is only a short introduction about Relative Wavelet Energy. Click here for some basic information about wavelet.

The energy of a discrete signal s(k) is defined as

and the relative energy is defined as

where is the total energy, which is calculated by adding here(Rosso, et al., 2006).
