Topology preserving
WebThe proposed topology-preserving loss function is differentiable and can be incorporated into end-to-end training of a deep neural network. Our method achieves much better performance on the Betti number error, which directly accounts for the topological correctness. It also performs superior on other topology-relevant metrics, e.g., the ... WebJan 6, 2024 · Topological distortion seriously affects spatial cognition. To solve this problem caused by the integration of vector features in discrete global grid systems (DGGs), a topology-preserving gridding method for vector features is proposed. The method proposed determines the topological distortion according to the relationship between grid …

WebJun 23, 2024 · Further, by searching the shortest path connecting two shapes we realize the registration with topology preserving. Finally, the numerical results on the Kimia shape dataset show that our proposed method achieves a better performance of registration than the conventional method. That is, the atlas-based strategy is valid for shape registration ... WebDynamic Network Embedding (DNE) is attracting much attention due to the time-evolving nature of many real-world networks. The main objective of DNE is to efficiently update node embeddings while preserving network topology at each timestep. The idea of most existing DNE methods is to capture the topological changes at or around the most affected nodes …
WebSep 24, 2015 · Since all flips preserve topology, such a sequence of flips is a topology-preserving deformation of the original image (sometimes called a homotopic deformation). The converse has also been proven: two images that are topologically equivalent in the sense of sharing isomorphic adjacency trees can always be transformed into each other … WebDec 19, 2024 · Knowledge of the road network topology is crucial for autonomous planning and navigation.
