source: build-install/usr/lib/python3.14/site-packages/scipy/signal/_spline_filters.py:481

Signature

def cspline2d(signal, lamb = 0.0, precision = -1.0)

Summary

Coefficients for 2-D cubic (3rd order) B-spline.

Extended Summary

Return the third-order B-spline coefficients over a regularly spaced input grid for the two-dimensional input image.

Parameters

signal : ndarray: The input signal.
lamb : float: Specifies the amount of smoothing in the transfer function.
precision : float: Specifies the precision for computing the infinite sum needed to apply mirror-symmetric boundary conditions.

Returns

output : ndarray: The filtered signal.
