scipy.signal.qspline2d

scipy.signal.qspline2d(input, lambda=0.0, precision=-1.0)

Coefficients for 2-D quadratic (2nd order) B-spline:

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

The filtered signal.
