WebMain Point: The authors introduce the normalized cut criterion and use it to segment images by modeling the pixels in the image as vertices in a graph, and then partitioning the graph so as to minimize the normalized cut. The normalized cut between disjoint partitions Aand B, or NCut(A;B) is de ned as: NCut= P u2A;v2B w(u;v) P q2A;t2V w(q;t ... Web“Min cuts” and “Normalized cuts”.
