ridge

wavelet power or coherence spectrum in the time/frequency domain

wavelet.spectrum

lower/upper band of neighboring values in the frequency domain used in the search for local maxima. Default: 5.

band

a scale factor applied to the global maximum defining a minimum level constraint. 
             Default: 0.1.

scale.factor


It finds the ridge of a wavelet power or coherence spectrum, subject to criteria concerning:
the band of neighboring values to be included in the search area for local maximization, 
and a scale factor applied to the global maximum defining a minimum level constraint.<p></p><p>This code is an efficient implementation of the basic concept of ridge determination by Huidong Tian and Bernard Cazelles 
(archived R package <code>WaveletCo</code>).
