Fonction qspline2d - module scipy.signal

Signature de la fonction qspline2d

Description

qspline2d.__doc__

out = 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
    ----------
    input : ndarray
        The input signal.
    lambda : 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 : ndarray
        The filtered signal.

    Examples
    --------
    Examples are given :ref:`in the tutorial <tutorial-signal-bsplines>`.
