- cupyx.scipy.ndimage.shift(input, shift, output=None, order=3, mode='constant', cval=0.0, prefilter=True)[source]#
Shift an array.
The array is shifted using spline interpolation of the requested order. Points outside the boundaries of the input are filled according to the given mode.
input (cupy.ndarray) – The input array.
shift (float or sequence) – The shift along the axes. If a float,
shiftis the same for each axis. If a sequence,
shiftshould contain one value for each axis.
output (cupy.ndarray or dtype) – The array in which to place the output, or the dtype of the returned array.
order (int) – The order of the spline interpolation, default is 3. Must be in the range 0-5.
mode (str) – Points outside the boundaries of the input are filled according to the given mode (
cval (scalar) – Value used for points outside the boundaries of the input if
mode='opencv'. Default is 0.0
prefilter (bool) – Determines if the input array is prefiltered with
spline_filterbefore interpolation. The default is True, which will create a temporary
float64array of filtered values if
order > 1. If setting this to False, the output will be slightly blurred if
order > 1, unless the input is prefiltered, i.e. it is the result of calling
spline_filteron the original input.
The shifted input.
- Return type
cupy.ndarray or None
