A flexible tiling of the time axis for adaptive wavelet packet decompositions
Antonio Pena, N.G. Prelcic, C. Serantes · 1997
A segmentation procedure of time sequences based on a time-frequency analysis is presented. The use of both a wavelet packet transform and the original time signal provides a set of spectral and time parameters that allows the algorithm to locate some proper break points to split the input frame into a discrete number of smaller segments. Some examples showing the performance of the method are also presented. An application to wavelet-based audio coding is also discussed.
