cupyx.scipy.signal.qspline2d#

cupyx.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:

  • input (ndarray) – The input signal.

  • lamb (float) – Specifies the amount of smoothing in the transfer function.

  • precision (float) – Specifies the precision for computing the infinite sum needed to apply mirror-symmetric boundary conditions.

Returns:

output – The filtered signal.

Return type:

ndarray
