Each frame of a magnitude spectrogram is normalized and treated as a distribution over frequency bins, from which the mean (centroid) is extracted per frame. More precisely, the centroid at frame t is defined as 1: centroid[t] = sum_k S[k, t] * freq[k] / (sum_j S[j, t]) where S is a magnitude spectrogram, and freq ...

In the DWT, each level is calculated by passing only the previous wavelet approximation coefficients (cAj) through discrete-time low- and high-pass quadrature mirror filters. However, in the WPD, both the detail (cDj (in the 1-D case), cHj, cVj, cDj (in the 2-D case)) and approximation coefficients are decomposed to create the full binary tree. For n levels of decomposition the WPD produces 2 different sets of coefficients (or nodes) as op… Webinterval and frequency band is computed and the relative energy is extracted.
