Return an image showing the differences between two images.

.. versionadded:: 0.16

Parameters
----------
image0, image1 : ndarray, shape (M, N)
    Images to process, must be of the same shape.

    .. versionchanged:: 0.24
        `image1` and `image2` were renamed into `image0` and `image1`
        respectively.
method : {'diff', 'blend', 'checkerboard'}, optional
    Method used for the comparison.
    Details are provided in the note section.

    .. versionchanged:: 0.24
        This parameter and following ones are keyword-only.
n_tiles : tuple, optional
    Used only for the `checkerboard` method. Specifies the number
    of tiles (row, column) to divide the image.

Returns
-------
comparison : ndarray, shape (M, N)
    Image showing the differences.

Notes
-----
``'diff'`` computes the absolute difference between the two images.
``'blend'`` computes the mean value.
``'checkerboard'`` makes tiles of dimension `n_tiles` that display
alternatively the first and the second image. Note that images must be
2-dimensional to be compared with the checkerboard method.
