wiener(im, mysize=None, noise=None)¶
Perform a Wiener filter on an N-dimensional array.
Apply a Wiener filter to the N-dimensional array im.
im (cupy.ndarray) – An N-dimensional array.
mysize (int or cupy.ndarray, optional) – A scalar or an N-length list giving the size of the Wiener filter window in each dimension. Elements of mysize should be odd. If mysize is a scalar, then this scalar is used as the size in each dimension.
noise (float, optional) – The noise-power to use. If None, then noise is estimated as the average of the local variance of the input.
Wiener filtered result with the same shape as im.
