OpenCV GrabCut: Foreground Segmentation and Extraction

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. WebThe earliest graph-based methods use ﬂxed thresholds and local measures in computing a segmentation. The work of Zahn [19] presents a segmentation method based on the minimum spanning tree (MST) of the graph. This method has been applied both to point clustering and to image segmentation.
