cspline2d#
- scipy.signal.cspline2d(signal, lamb=0.0, precision=-1.0)[source]#
- 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.
