The Detection of DENIS Galaxies

Abstract

Using simulated images, we test various methods, for the homogeneous detection of objects in DENIS images. The optimal detection limits depend on the object type and the sky background, but little on the PSF or the smoothing filter used to increase the signal-to-noise of the images.
