- scipy.signal.qspline2d(signal, lamb=0.0, precision=-1.0)[source]#
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.
- 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.
