Fig 2. Extraction of C. elegans 3D midline skeleton from a light field image.
(a) On axis pinhole view with segmentation mask outline shown in green. (b) Combined depth estimates within the segmentation mask displayed using a colour scale. (c) Final extracted midline skeleton of the organism comprised of 25 linear segments. The orientation of each segment is described by an azimuthal (θ) and polar angle (ϕ).
