Hierarchical bspline refinement

Web1 de dez. de 2011 · Local hierarchical refinement. The idea of hierarchical refinement in isogeometric analysis is simply to replace the standard NURBS basis in (15) by a hierarchical one. The hierarchical basis of Definition 1 is defined on Ω 0, possesses favorable properties by construction and is thus a promising candidate for our objective. Web25 de fev. de 2024 · Then the hierarchical consistency loss without refinement strategy is introduced in ML-MT-NR. As illustrated in Table 2, with hierarchical consistency on multiple targets, ML-MT-NR gains an improvement of 0.8% Dice. With the refinement consistency guidance, ML-MT achieves 90.57% Dice and further improves the performance by 0.5%.
