Transverse Strains in Muscle Fascicles during Voluntary Contraction: A 2D Frequency Decomposition of B-Mode Ultrasound Images
Figure 3
Error Analysis for the Selection of the Moment of Frequency, . The correlation between the inclination angle determined by manual digitization, , and the inclination angle determined from the discrete Fourier transform, , is shown for different values of (a). The root-mean-square error between these terms is shown in (b). Points show the mean ± SEM ().
