Method and apparatus for denoising of physiological signals
Abstract:
Certain aspects of the present disclosure relate to techniques for denoising of physiological signals. A signal (e.g., physiological signal) comprising at least two signal channels can be decomposed (e.g., using independent component analysis (ICA)) into at least two independent components. Then, independent component (IC) denoising can be applied to estimate which of the at least two independent components belong to a signal space and which of the at least two independent components belong to a noise space using a statistical metric associated with the at least two signal channels. A de-noised version of the signal can be generated by preserving in the signal only one or more independent components of the at least two independent components belonging to the signal space.
