23.06.2020 · (b) Graph Neural Network: we design a GNN module shown in purple to model the object-object interactions through feature aggregation. The detection head uses the node feature from anchors to predict bounding boxes, while the data association head learns to regress the similarity matrix based on the edge features.

Graph Neural Networks. Graph neural networks [24, 49, 51, 10, 1] can model dependencies among nodes flexibly, and can be applied to scenarios with irregular data struc-tures. Graph convolutional networks (GCN [20]) perform spectral convolutions on graphs to propagate information a-mong nodes. Graph attention networks (GAT [49]) leverage

Mar 02, 2020 · The graph neural network then outputs the vertex features or repeats the process in the next iteration. In the case of object detection, we design the GNN to refine a vertex’s state to include information about the object where the vertex belongs. Towards this goal, we re-write Equation ( 2) to refine a vertex’s state using its neighbors’ states:

19.06.2020 · Abstract: In this paper, we propose a graph neural network to detect objects from a LiDAR point cloud. Towards this end, we encode the point cloud efficiently in a fixed radius near-neighbors graph. We design a graph neural network, named Point-GNN, to predict the category and shape of the object that each vertex in the graph belongs to.

Sep 01, 2020 · It is the job of our graphical model to capture higher-order features between two nodes (object detections) by performing message passing. Once the message passing is complete and the edges have...

06.12.2021 · Graph Neural Networks (GNNs) are a class of deep learning methods designed to perform inference on data described by graphs. GNNs are neural networks that can be directly applied to graphs, and provide an easy way to do node-level, edge-level, and graph-level prediction tasks. GNNs can do what Convolutional Neural Networks (CNNs) failed to do.

Convolutional neural networks that detect objects from images rely on the convolution operation. While the con- volution operation is efficient, it requires a ...

Keywords: Salient object detection, RGB-D perception, graph neural networks 1 Introduction Salient object detection is the crux to dozens of high-level AI tasks such as object detection or classi cation [52,80,69], weakly-supervised semantic segmen- tation [30,63], semantic correspondences [77] and others [35,72,71].

We design a graph neural net- work, named Point-GNN, to predict the category and shape of the object that each vertex in the graph belongs to. In Point-GNN, we propose an auto-registration mechanism to reduce translation variance, and also design a box merg- ing and scoring operation to combine detections from mul- tiple vertices accurately.

Graph Neural Networks for Object Detection Even though graph neural networks (GNNs) are a rel- atively new direction in research, they have been rapidly adopted for object detection. In [11] spatial relationships between 3D proposals are used in a graph in order to con- sider the whole scene structure for the ・]al box predictions.
