Fig 5. The elevation trajectories from Fig 4 warped with dynamic time warping using different step patterns.

(a)-(b) Symmetric step pattern denotes the so-called White-Neely step pattern that has no local constraints, (c)-(d) asymmetric step pattern denotes a slope-constrained step pattern where local slopes are required to be between 0 and 2, and (e)-(f) Sakoe-Chiba step pattern denotes the asymmetric step pattern proposed in [24, Table I] with a slope constraint of 2.
