Methods and systems for discriminating bands in scalograms
First Claim
1. A method comprising:
- generating a scalogram based at least in part on a continuous wavelet transform of a signal;
determining whether a first band of scales in the scalogram is negatively affected by a second band of scales; and
extracting the first band of scales in response to determining that the first band is negatively affected by the second band.

Abstract
The present disclosure is directed towards embodiments of systems and methods for discriminating (e.g., masking out) scale bands that are determined to be not of interest from a scalogram derived from a continuous wavelet transform of a signal. Techniques for determining whether a scale band is not of interest include, for example, determining whether a scale band'"'"'s amplitude is being modulated by one or more other bands in the scalogram. Another technique involves determining whether a scale band is located between two other bands and has energy less than that of its neighboring bands. Another technique involves determining whether a scale band is located at about half the scale of another, more dominant (i.e., higher energy) band.
