WebSep 1, 2014 · A geodesic line is the shortest path between two points on a curved surface, like the Earth. They are the analogue of a straight line on a plane surface or whose sectioning plane at all points along the line remains normal to the surface. It is a way of showing distance on an ellipsoid whilst that distance is being projected onto a flat surface.

WebMay 11, 2024 · According to the aforementioned discussion, a novel low-dimensional embedding algorithm based on the t-copula and Wasserstein distance is presented. Algorithm 1 shows the detailed process. In Algorithm 1, Steps 4–8 are to compute the pairwise similarity in high-dimensional space, whose time complexity is O ( N 2 2). Webdefine the optimal basis for geodesic distance representa-tion, and relate it to the LBO basis. Next, Section 4 deals with efficiently approximating the geodesic distance basis without actually computing all pairwise geodesic distances. The induced geodesic distance descriptor is defined in Sec-tion 5, where we show how it can be used to ...
In the mathematical field of graph theory, the distance between two vertices in a graph is the number of edges in a shortest path (also called a graph geodesic) connecting them. This is also known as the geodesic distance or shortest-path distance. Notice that there may be more than one shortest path between two vertices. If there is no path connecting the two vertices, i.e., if they belong to different connected components, then conventionally the distance is defined as infinite.
