Mathematical Morphology: Star/Galaxy Differentiation & Galaxy Morphology Classification

Moore, Jason A.; Pimbblet, Kevin A.; Drinkwater, Michael J.

We present an application of Mathematical Morphology (MM) for the classification of astronomical objects, both for star/galaxy differentiation and galaxy morphology classification. We demonstrate that, for CCD images, 99.3+/-3.8% of galaxies can be separated from stars using MM, with 19.4+/-7.9% of the stars being misclassified. We demonstrate tha…
