- cupyx.scipy.ndimage.extrema(input, labels=None, index=None)[source]#
Calculate the minimums and maximums of the values of an array at labels, along with their positions.
input (cupy.ndarray) – N-D image data to process.
labels (cupy.ndarray, optional) – Labels of features in input. If not None, must be same shape as input.
index (int or sequence of ints, optional) – Labels to include in output. If None (default), all values where non-zero labels are used.
A tuple that contains the following values.
minimums (cupy.ndarray): Values of minimums in each feature.
maximums (cupy.ndarray): Values of maximums in each feature.
min_positions (tuple or list of tuples): Each tuple gives the N-D coordinates of the corresponding minimum.
max_positions (tuple or list of tuples): Each tuple gives the N-D coordinates of the corresponding maximum.
