Comparison between two layers ${\mathscr{H}}_{k-1}$, ${\mathscr{H}}_k$ and their intersection. The layers are ordered in terms of depth (i.e., ${\mathscr{H}}_{k-1}$ corresponds to a smaller depth than ${\mathscr{H}}_k$). (a) A set of EPI lines related to constant disparity $\Delta p_k$. The collection of EPI lines carve out a layer ${\mathscr{H}}_k$. Observe that the complete segmentation of the layer can be defined by a boundary on one viewpoint projected to the remaining frames. (b) ${\mathscr{H}}_{k-1}$ modelled by a constant disparity $\Delta p_{k-1}$. (c) When the two layers intersect, ${\mathscr{H}}_{k-1}$ will occlude ${\mathscr{H}}_k$ as it is modelled by a smaller depth. We define the visible volumes with ${\mathscr{H}}_{k-1}^{\mathcal{V}}$ and ${\mathscr{H}}_k^{\mathcal{V}}$.
