cupyx.scipy.ndimage.standard_deviation#

cupyx.scipy.ndimage.standard_deviation(input, labels=None, index=None)[source]#

Calculates the standard deviation of the values of an n-D image array, optionally at specified sub-regions.

Parameters:

input (cupy.ndarray) – Nd-image data to process.
labels (cupy.ndarray or None) – Labels defining sub-regions in input. If not None, must be same shape as input.
index (cupy.ndarray or None) – labels to include in output. If None (default), all values where labels is non-zero are used.

Returns:

standard deviation of values, for each sub-region if labels and index are specified.

Return type:
