scipy.signal.cspline2d(input, lambda=0.0, precision=-1.0)

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

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

Parameters
inputndarray

The input signal.

lambdafloat

Specifies the amount of smoothing in the transfer function.

precisionfloat

Specifies the precision for computing the infinite sum needed to apply mirror- symmetric boundary conditions.

Returns
outputndarray

The filtered signal.
