WebMany tasks in computer vision involve assigning a label (such as disparity) to every pixel. A common constraint is that the labels should vary smoothly almost everywhere while preserving sharp discontinuities that may exist, e.g., at object boundaries. These tasks are naturally stated in terms of energy minimization. The authors consider a wide class of … WebMinimum Normalized Cut Image Segmentation • Normalized cut [1,2] computes the cut cost as a fraction of the total edge connections to all the nodes in the graph. Advantage: Being an unbiased measure, the Ncut value with respect to the isolated nodes will be of a large percentage compared to the total connection from small set to all other nodes.

WebA graph is a set of nodes (sometimes called vertices) with edges between them. See Figure 9-1 for an example. [] The edges can be directed (as illustrated with arrows in Figure 9-1) or undirected, and may have weights associated with them..
