Warping Complexity

Computes the geodesic distance of a warping function from the identity, measuring how much phase variability the warp introduces.

Usage

warp.complexity(gamma, argvals)

Arguments

gamma

Numeric vector of warping function values.

argvals

Numeric vector of grid points.

Value

A scalar complexity value (0 = identity warp).

Examples

t <- seq(0, 1, length.out = 20)
warp.complexity(t^2, t)
#> [1] 0.349855
warp.complexity(t, t)  # identity = 0
#> [1] 0
