Return the second-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
