/**
 *
 * @defgroup hdrl_catalogue     Object catalogue
 *
 * @brief
 *   This module provides algorithms to build an objects catalogue.
 *   Depending on the value of the control parameter "resulttype", additional
 *   products may be generated: a full catalogue, the background map, the
 *   segmentation map.
 *
 * \par Brief algorithm description:
 *
 * A local sky background is estimated and removed
 *
 * Objects and blends are detected and the image pixels are assigned to each
 * object (or blend) they belong to.
 *
 * On the objects it is performed astrometry, photometry and shape analysis.
