The Babelsberg image processing system which will be used for the new automated measuring machine ASAG (Astronomisches Auswertegerät) includes as special feature an adaptive filtering technique. This technique allows a reduction of noise and the determination of the background in astronomical pictures and has already been used for the surface photometry of galaxies on Schmidt plates. For astrometric purposes a method of detecting and separating images in two‐dimensional measuring rasters was developed within the frame of the ASAG software and algorithms.
