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. z Images must have the same shape.rblendg? checkerboardzIImages must be 2-dimensional to be compared with the checkerboard method.FrrTzKWrong value for `method`.
