The low surface brightness Universe (µr ~ 28.5-29 mag arcsec-2) remains almost unexplored. Its analysis is a technical challenge from the observational point of view but also requires a very sophisticated data treatment. The incoming deep and wide surveys as the LSST or Euclid, will allow us to explore low surface brightness objects such as stellar haloes of galaxies, intra-cluster light or Galactic cirrus. Thus, it is necessary to develop new techniques and software procedures that improve the reduction of huge amounts of astronomical images and prevent the removal of large and diffuse astrophysical structures.
