sepfir2d

scipy.signal.sepfir2d(input, hrow, hcol)

Convolve with a 2-D separable FIR filter.

Convolve the rank-2 input array with the separable filter defined by the rank-1 arrays hrow, and hcol. Mirror symmetric boundary conditions are assumed. This function can be used to find an image given its B-spline representation.

Parameters:

inputndarray

The input signal. Must be a rank-2 array.

hrowndarray

A rank-1 array defining the row direction of the filter. Must be odd-length

hcolndarray

A rank-1 array defining the column direction of the filter. Must be odd-length

Returns:

outputndarray

The filtered signal.
