cupyx.scipy.ndimage.variance

cupyx.scipy.ndimage.variance(input, labels=None, index=None)

Calculates the variance 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

Values of variance, for each sub-region if

labels and index are specified.

Return type

variance (cupy.ndarray)
