Calculate elastic shape distance between two curves beta1 and beta2
calc_shape_dist(beta1, beta2, mode = "O", scale = F)
beta1 |
array describing curve1 (n,T) |
beta2 |
array describing curve |
mode |
Open ("O") or Closed ("C") curves |
scale |
Include scale (default =F) |
Returns a list containing
d |
geodesic distance |
dx |
phase distance |
