Resampling

Module with routines for data and curve resampling and smoothing based on splines.

resample(curve, n_points=None, smooth=0, periodic=False, derivative=0, order=5, iterations=1)

Resample a curve using equidistant points along a curve.

Arguments

curvemxd array

Coordinates for the reference points of the curve.

n_pointsint

Number of equidistant points to evaluate the curve on.

smoothint or float

Smoothness factor.

periodicbool

If True, assume the curve is a closed loop.

derivativeint

If > 0, return the n-th derivative of the curve.

orderint

The spline order to use to interpolate the curve.

iterationsint

Iterate the resampling process this amount of time.

Returns

curvenxd array

Resampled curve along n_points equidistant points.

resample_1d(data, n_points=None, smooth=0, periodic=False, derivative=0, order=5, iterations=0)
