(sequence or int): Desired output size of the crop. If size is an
            int instead of sequence like (h, w), a square crop (size, size) is
            made. If provided a sequence of length 1, it will be interpreted as (size[0], size[0]).

    Returns:
       tuple: tuple (tl, tr, bl, br, center)
       Corresponding top left, top right, bottom left, bottom right and center crop.
