Leg crossover detection: (a) shows COM signal (full-black line), detected cycle starts (dashed-red vertical lines), and leg crossover locations (full-magenta vertical lines). (b) shows front (blue) and rear (green) thigh angle signals as extracted from skeleton. (c) shows thigh angle signals interpolated into left (blue) and right (green) thigh angles. axis denotes time in frames and axis represents normalized signal values.
