We lose a lot of accuracy when compared to other established segmentation algorithms. ... WebFeb 28, 2024 · In the graph-based approach, a segmentation S is a partition of V into components such that each component (or region) C ∈ S corresponds to a connected component in a graph G0 = (V, E0), where E0 ⊆ E. In other words, any segmentation is induced by a subset of the edges in E.
