Web21 de jul. de 2024 · Hierarchical Feature Learning on Point Sets. PointNet++. So, the authors introduce the concept of Hierarchical Feature Learning, and for that we need to take local context into account. Web26 de out. de 2024 · In this paper, we advocate the use of modified Hausdorff distance as a shape-aware distance measure for calculating point convolutional responses. The technique we present, coined Hausdorff point convolution (HPC), is shape-aware. We show that HPC constitutes a powerful point feature learning with a rather compact set of only …

Web7 de jun. de 2024 · In this work, we introduce a hierarchical neural network that applies PointNet recursively on a nested partitioning of the input point set. By exploiting metric space distances, our network is able to learn local features with increasing contextual scales. With further observation that point sets are usually sampled with varying … Web15 de mar. de 2024 · Feature learning on point clouds has shown great promise, with the introduction of effective and generalizable deep learning frameworks such as pointnet++. Thus far, however, point features have been abstracted in an independent and isolated manner, ignoring the relative layout of neighboring points as well as their features. In the …
