Illustration of the method used to reconstruct physical filaments of bar width (W_b = 14 px). Top left: initial map A of the G210 field. Top middle: binary map C from the first step of FilDReaMS applied to map A (same pixels as in the top panel of Fig. 5). Bottom left: pixels at which at least one significant bar-like filament of bar width W_b is detected (same pixels as in the bottom panel of Fig. 5). Bottom middle: binary map C′ in which the model bars associated with all the significant bar-like filaments are set to 1 and the background is set to 0. Right: filament mask obtained by multiplying C by C′. Rightmost: reconstructed physical filaments obtained by applying the filament mask to the initial map A.
