Foot scanning and deformation estimation using time-of-flight cameras

Combined with the results of input signals, fv always deviated from fGRF with a discrepancy reached 34– 40Hz during DJ for both shoes; on the contrary, during PL, fGRF would move towards fv, which may induce to create a resonance situation (a dashed frame in Figure 2). Furthermore, fGRF of the control condition was much closer to the resonance frequency compared with the basketball shoe for most subjects (Figure 2).
