Before Change

    c_mask = np.ascontiguousarray(mask, dtype=np.int8).ravel()

After Change

    pad_width = [(p, p) for p in offset]
    image = np.pad(image, pad_width, mode="constant")
    mask = np.pad(mask, pad_width, mode="constant").ravel()
    output = np.pad(markers, pad_width, mode="constant")

    flat_neighborhood = _compute_neighbors(image, connectivity, offset)
    marker_locations = np.flatnonzero(output).astype(np.int32)
