`scipy.signal.``cspline2d`()

  cspline2d(input {, lambda, precision}) -> ck

  Description:

  > Return the third-order B-spline coefficients over a regularly spacedi input grid for the two-dimensional input image. The lambda argument specifies the amount of smoothing. The precision argument allows specifying the precision used when computing the infinite sum needed to apply mirror- symmetric boundary conditions.
