ABSTRACT
This paper deals with the use of the vector levelings for cod-
ing color images. This class of morphological connected
filters suppresses details but preserves the contours of the
remaining objects. If the color images are filtered by inde-
pendently leveling each color component, new colors may
be introduced. In order to avoid this drawback, a total or-
der must be imposed on the color vectors. A comparative
study has been drawn for various lexicographical orders in
the RGB and the HLS color systems. These filters can be
especially useful as a preprocessing step for improving the
compression of color images.
