Graph cuts in computer vision
Did you know?
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 … WebThis class will provide the introduction to fundamental concepts in computer Vision. Topics in this class include camera pose estimation, 3D reconstruction, feature detectors and descriptors, object recognition using vocabulary tree, segmentation, stereo matching, graph cuts, belief propagation, and a brief introduction to deep neural networks.

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.. A graph cut is the partitioning of a directed graph into two disjoint sets. Graph cuts can be used for solving many different … WebJan 15, 2024 · In computer vision, an image is usually modeled as a graph wherein …
