Comparison of the segmented maps obtained using the PE-UNet-L and UNet versions centred on a high column density region of the plane at the location around (l, b) = 144°, 0.3°. The difference between the result of the two segmented maps (PE-UNet-L – UNet) is shown (left) with the corresponding column density map (middle) and the local normalized column density map (right). The white features seen on the left map correspond to features detected only with the PE-UNet-L.
