This paper proposes a new application of the Hilbert-Huang transform (HHT). Pupillogram recording were analyzed through the non-traditional HHT to investigate patterns in the time-frequency parameters of Spontaneous Pupillary Oscillation (SPO) signals. The traditional Fourier transform is only useful for linear stationary signals analysis, but the HHT was designed for the analysis of non-linear and...
In this work a new application of the Hilbert-Huang transform (HHT) is proposed. Recordings of pupillograms were analyzed through the non-traditional HHT, in order to investigate patterns in the time-frequency parameters of the spontaneous pupillary oscillation (SPO) signals. Unlike the traditional Fourier transform, which is only useful for the analysis of linear stationary signals, the HHT was designed...
