- cupyx.scipy.ndimage.binary_erosion(input, structure=None, iterations=1, mask=None, output=None, border_value=0, origin=0, brute_force=False)#
Multidimensional binary erosion with a given structuring element.
Binary erosion is a mathematical morphology operation used for image processing.
input (cupy.ndarray) – The input binary array_like to be eroded. Non-zero (True) elements form the subset to be eroded.
structure (cupy.ndarray, optional) – The structuring element used for the erosion. 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 erosion is repeated
iterationstimes (one, by default). If iterations is less than 1, the erosion 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)
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 (eroded) in the current iteration; if True all pixels are considered as candidates for erosion, regardless of what happened in the previous iteration.
The result of binary erosion.
