abstract = "We deal in this work with a broadly studied topic in astronomical
imaging, namely the star/galaxy discrimination problem. Through
the use of Mathematical Morphology, we propose an original
approach to the characterization of these astronomical objects,
which is based on gray-level shape information. The main steps in
our method are image pre-processing, segmentation and feature
extraction, all of which employ Mathematical Morphology tools that
were implemented using the MMach toolbox for the Khoros system. We
present a comparison between our segmentation results, based on
the watershed method, and those of a classical software package
SExtractor. The shape information is extracted through the use of
the gray-level morphological pattern spectrum, which yields very
satisfactory shape features, that promise to be very suitable for
future work in neural-network automatic classification.",
