20.500.12556/DKUM-92272 A novel radial basis function description of a smooth implicit surface for musculoskeletal modelling As musculoskeletal illnesses continue to increase, practical computerised muscle modelling is crucial. This paper addresses this concern by proposing a mathematical model for a dynamic 3D geometrical surface representation of muscles using a Radial Basis Function (RBF) approximation technique. The objective is to obtain a smoother surface while minimising data use, contrasting it from classical polygonal (e.g. triangular) surface mesh models or volumetric (e.g. tetrahedral) mesh models. The paper uses RBF implicit surface description to describe static surface generation and dynamic surface deformations based on its spatial curvature preservation during the deformation. The novel method is tested on multiple data sets, and the experiments show promising results according to the introduced metrics. radial basis function muscle model gradient decsent curvature mean curvature Gaussian RBF radialna snovna funkcija mišični modeli ukrivljenost povprečna ukrivljenost true false true Vilnius University, Institute of Data Science and Digital Technologies Angleški jezik Slovenski jezik https://informatica.vu.lt/journal/INFORMATICA © 2024 Vilnius University Članek v reviji 2025-03-26 14:16:07 2025-03-26 14:16:07 2026-01-15 12:30:34 0000-00-00 00:00:00 2024 0 0 str. 721-750 iss. 4 Vol. 35 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-06-01 2024-09-01 2024-10-16 004.9 230334467 10.15388/24-INFOR571 0868-4952 infor571.pdf infor571.pdf 1 B089007387EB31228FFF2FFBB4FE874C 1126405af41a6f1bf0d5ee2d48eb76c4c9aec6000b8ac62601416055445135ec 120aefb0-0a45-11f0-af23-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189682 https://informatica.vu.lt/journal/INFORMATICA/article/1352/info 0 7a863e07-f205-11f0-9ca2-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=202051 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
