Abstract

See full text

A method of digital signal feature extraction comprises steps of: (a) segmenting samples of the digital signal to form a set of groupings each comprising a subset of the samples, with each grouping having endpoints spaced apart by a current grouping size; (b) applying an operator, which is associated with the desired feature to be extracted, to the subset of the samples of each grouping to derive a representative value therefor corresponding to the grouping size; and (c) repeating step a), but based on a different grouping size, and repeating step b) on the set of groupings formed based on the different grouping size, with the operator being adapted to correspond to the different grouping size. The set of groupings formed in step a) collectively includes all of the samples of the signal. One endpoint of at least one grouping is intermediate the endpoints of another one of the groupings.
