A python package for fitting splines. Developed by the EPFL Center for Imaging as part of a collaboration with the Uhlmann Group at EMBL-EBI in Feb 2024.
- Flexible spline fitting for various applications.
- Support for many spline types in any dimesnionality.
- High-perfomance implementation in Python
- Extensive documentation with examples
You can install splinebox
via pip:
pip install splinebox
Here is a minimal example of a cubic B-spline in 2D with 3 knots.
import splinebox
import numpy as np
import matplotlib.pyplot as plt
n_knots = 4
spline = splinebox.spline_curves.Spline(M=n_knots, basis_function=splinebox.basis_functions.B3(), closed=True)
spline.knots = np.array([[1, 2], [3, 2], [4, 3], [1, 1]])
t = np.linspace(0, n_knots, 100)
vals = spline.eval(t, derivative=0)
plt.scatter(spline.knots[:, 0], spline.knots[:, 1])
plt.plot(vals[:, 0], vals[:, 1])
plt.show()
