WebJan 6, 2012 · A fast and efficient graph-based segmentation algorithm can be found here. This algorithm is described in the paper of Pedro F. Felzenszwalb and Daniel P. Huttenlocher, Efficient Graph-Based Image Segmentation , IJCV 2004. It works fast and capable of extracting regions with roughly similar intensities. 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.
