ab: Summary: In this paper a multiscale study based on the use of morphological
    connected transformations is presented. In particular, the
    morphological opening and closing by reconstruction are used as
    connected transformations. These transformations have the
    characteristic of preserving contours without introducing new
    information, in addition to smoothing the processed image as the size
    of the structuring element increases. Due to this, both connected
    filters and the identity are used as primitives to introduce two
    operators that allow a multiscale treatment to the processed image in
    accordance with the scale parameter. The multiscale morphological
    operators are called opening-closing by reconstruction and
    closing-opening by reconstruction, respectively. In the case of the
    opening-closing by reconstruction transformation, the propagation of
    extrema when the structuring element enlarges has an interesting
    behavior. In addition, the fingerprints of the image given as a
    function of regional maxima, regional minima and scale parameter are
    defined. Finally, the proposals of this work are illustrated with some
    examples.
