Web22 de set. de 2024 · Other local refinement techniques, such as hierarchical B-splines, are based on subdivision, a technique that can be derived from knot insertion. In the following, we will focus on these hierarchical concepts, since, in the authors’ opinion, they provide a very natural extension to conventional B-splines. Web3 de mai. de 2024 · Metric-based few-shot learning categorizes unseen query instances by measuring their distance to the categories appearing in the given support set. To facilitate distance measurement, prototypes are used to approximate the representations of categories. However, we find prototypical representations are generally not …

In particular, a novel multi-stage and dual-path network structure is designed to estimate the salient edges and regions from the low-level and high-level … Web21 de set. de 2024 · a discussion on adaptive spline representations based on hierarchical refinement. There exists a huge amount of literature about the first two items including some well-established books; see, e.g., [6, 26, 45] and references therein.

Web1 de set. de 2024 · The hierarchical approach to adaptive spline refinement has lately been revisited, resulting in the introduction of truncated hierarchical B-splines [10]. Besides forming a convex partition of unity, they provide good stability properties, algebraic completeness under mild assumptions on the refinement procedure, and optimal …
