Dgcnn edgeconv
WebNov 30, 2024 · DGCNN stands for dynamic graph convolutional neural network. As Fig. 27.3, inspired by PointNet, DGCNN adds EdgeConv (edge convolution) to achieve a better understanding of point cloud local features.EdgeConv refers to the convolution of edges between points. Instead of using individual points like PointNet, DGCNN utilizes local … WebA. Attention EdgeConv EdgeConv, proposed by [3], is an effective method for capturing local information. When calculating features of one particular point, EdgeConv takes the information of that point and its K nearest points. With this technique, the points can form a small local graph within a small area, providing local & & ' ()*++,- . /01 ...
