cspline2d

scipy.signal.cspline2d(signal, lamb=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.

lambfloat

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.
