One can roughly picture the cosmos as a gas of galaxies, freely distributed and isotropically moving. Yet astronomical observations have shown that this repartition is not so homogeneous. Galaxies cluster in long structures, called filaments, and leave between those filaments huge voids. The filaments, which only represents 10% of the universe, are organized in a complicated three dimensional spider-like network. The goal of my internship is to extract this filament network from astronomical catalogues of galaxies. The extraction method relies on the Quality Candy model, previously developed by the Ariana team for the road extraction in remote sensed images. Here is a link to a presentation (in French) of the Quality Candy.
