Visualization of the set of simulations SimSet 4 for ideal filaments, showing how well FilDReaMS recovers the widths W_b of overlapping filaments with different widths, aspect ratios, and intensities. Top left: one of the 100 test maps, containing 64 ideal filaments, with width W_b = 9 px or 15 px, aspect ratio in the range [3, 10], and intensity in the range [0.2,5]. Top right: corresponding map of all the filaments detected and reconstructed by FilDReaMS. Bottom: number of pixels, N_pix, whose most significant bar width is , normalized to the number of pixels in the map, N_map, as a function of .
