Method and Device for removing noise from Functional near-infrared spectroscopy signal

摘要

As an exemplary embodiment of the present invention, a device for removing noise from a functional near-infrared spectroscopy (fNIRS) signal comprises: an fNIRS signal obtaining unit obtaining a hemodynamic response signal from a plurality of measurement channels outputted when radiating a near-field signal to a plurality of positions of a scalp by fNIRS; a multi-threshold value calculating unit calculating a threshold value Γ_m for each wavelet threshold band used in a wavelet contraction method; and a noise removing unit removing noise by applying the calculated threshold value Γ_m to each wavelet threshold band.
