find_optimal_t function

Optimal alignment to a smooth curve

Optimal alignment to a smooth curve

Finds optimal alignment for a discrete open srv curve to a smooth curve

find_optimal_t(srv_curve, s, q, initial_t = s, eps = 10 * .Machine$double.eps)

Arguments

  • srv_curve: srv transformation of the smooth curve, needs to be vectorized
  • s: time points for q, first has to be 0, last has to be 1
  • q: square root velocity vectors, one less than time points in s
  • initial_t: starting value for the optimization algorithm
  • eps: convergence tolerance

Returns

optimal time points for q, without first value 0 and last value 1, optimal time points have the distance of the observation to the srv_curve as an attribute
