Figure 10

Continuous Wavelet Transform (CWT) relative to the -axis acceleration signal illustrated in Figure 8(a). The upper plot represents the acceleration signal along the -axis during a walking activity. The central plot shows the CWT coefficients of the considered signal with a 1–16 scale range and the Mexican hat wavelet. The lower plot depicts the local maxima of the performed CWT.
