How do you calculate normalized cut?

solution to the normalized cut problem. one can subdivide the existing graph using the eigen vector with the next smallest eigen value. then placing the data into W and D. Solve (D-W)x=λDx for eigen vectors with the smallest eigenvalues.

What is a normalized cut?

The normalized cut criterion measures both the total dissimilarity between the di erent groups as well as the total similarity within the groups. We show that an e cient computational technique based on a generalized eigenvalue problem can be used to optimize this criterion.

Is graph cut algorithm a segmentation technique?

Graph cut is a semiautomatic segmentation technique that you can use to segment an image into foreground and background elements. Graph cut segmentation does not require good initialization. You draw lines on the image, called scribbles, to identify what you want in the foreground and what you want in the background.

What is graph based segmentation?

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 G = (V,E ), where E ⊆ E. In other words, any segmentation is induced by a subset of the edges in E.
