WebJul 24, 2024 · In the present paper, we propose to define the Shepard interpolation by using the geodesic distance. The geodesic distance between a pair of points is the length of the shortest geodesic line, and geodesic line is the generalization of straight line in the Euclidean geometry to general spaces, for instance 3D surfaces. When the shape of … WebNov 6, 2024 · In recent years, optimization on manifolds is widely concerned due to its advantages. For example, some constrained optimization problems in Euclidean space can be regarded as unconstrained problems on manifolds, as well as some nonconvex problems can be transferred to geodesic convex problems by endowing with suitable Riemannian …
• A subset of n-dimensional Euclidean space E with its usual flat metric is geodesically convex if and only if it is convex in the usual sense, and similarly for functions. • The "northern hemisphere" of the 2-dimensional sphere S with its usual metric is geodesically convex. However, the subset A of S consisting of those points with latitude further north than 45° south is not geodesically convex, since the minimizing geodesic (great circle) arc joining two distinct points on the southern boun… WebOct 27, 2024 · In the spirit of standard convex optimization, we develop two general methods in the geodesic setting, a first order and a second order method, which respectively receive first and second order information on the "derivatives" of the function to be optimized. These in particular subsume all past results.
