WebIn the mathematical discipline of graph theory, a matching or independent edge set in an undirected graph is a set of edges without common vertices. [1] In other words, a subset of the edges is a matching if each vertex appears in at most one edge of that matching. Finding a matching in a bipartite graph can be treated as a network flow problem.

WebJun 6, 2010 · The spatial information that can be recovered from a planar image is thus subject to projective constraints. Stereo vision, camera calibration, shape from motion, and many other computer vision techniques utilize projective geometry. It also has many applications in computational geometry, mostly arising due to duality.

WebA graph is said to be planar if it can be drawn on a flat plane without any of the edges crossing. If so, one can define a face of the graph as any region bounded by edges and containing no edges on the interior.
