Specifies the number of tiles (row, column) to divide the image. Returns ------- comparison : 2-D array 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. z Images must have the same shape.rÚblendgà?Ú checkerboardFrréTzKWrong value for `method`.
