Query: The Detection of DENIS Galaxies   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.
