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.
