Paper Abstract

The advent of large format CCD detectors is producing a data flow which cannot be handled with traditional interactive software tools and to be effectively exploited need automatic tools for catalogue extraction and analysis. NExt (Neural Extractor) is a neural network based package capable to perform in a fully automatic way both object detection and star/galaxy classification on large format astronomical images. In this paper we shortly summarize the main aspects of the package stressing some innovative aspect of the procedure implemented to perform the automatic extraction of the data set to be used for the training.
