WebOct 28, 2024 · To this end, we propose a new neural network module dubbed EdgeConv suitable for CNN-based high-level tasks on point clouds including classification and segmentation. EdgeConv is differentiable ... WebApr 7, 2024 · Geometric attentional EdgeConv. To solve the problems mentioned above, we propose an approach to combine geometric level and feature level information in feature learning of point cloud. We introduce a geometric attentional operation to EdgeConv, in which the geometric information is modeled as a weight for the output of original …
WebEdgeConv (DGCNN) dynamically updates the graph. That means the kNN is not fixed. Proximity in feature space differs from proximity in the input, leading to nonclocal diffusion of information throughout the point cloud. Dynamic update of the graph makes sense, but ablation test shows it only gives minor improvement.
