- cupyx.scipy.ndimage.binary_dilation(input, structure=None, iterations=1, mask=None, output=None, border_value=0, origin=0, brute_force=False)[source]#
Multidimensional binary dilation with the given structuring element.
input (cupy.ndarray) – The input binary array_like to be dilated. Non-zero (True) elements form the subset to be dilated.
structure (cupy.ndarray, optional) – The structuring element used for the dilation. Non-zero elements are considered True. If no structuring element is provided an element is generated with a square connectivity equal to one. (Default value = None).
iterations (int, optional) – The dilation is repeated
iterationstimes (one, by default). If iterations is less than 1, the dilation is repeated until the result does not change anymore. Only an integer of iterations is accepted.
mask (cupy.ndarray or None, optional) – If a mask is given, only those elements with a True value at the corresponding mask element are modified at each iteration. (Default value = None)
output (cupy.ndarray, optional) – Array of the same shape as input, into which the output is placed. By default, a new array is created.
border_value (int (cast to 0 or 1), optional) – Value at the border in the output array. (Default value = 0)
origin (int or tuple of ints, optional) – Placement of the filter, by default 0.
brute_force (boolean, optional) – Memory condition: if False, only the pixels whose value was changed in the last iteration are tracked as candidates to be updated (dilated) in the current iteration; if True all pixels are considered as candidates for dilation, regardless of what happened in the previous iteration.
The result of binary dilation.
