VoxelNeXt: Fully Sparse VoxelNet for 3D Object Detection and Tracking

Yukang Chen, Jianhui Liu, Xiangyu Zhang +2

3D object detectors usually rely on hand-crafted proxies, e.g., anchors or centers, and translate well-studied 2D frameworks to 3D. Thus, sparse voxel features need to be densified…

IST-Net: Prior-free Category-level Pose Estimation with Implicit Space Transformation

Jianhui Liu, Yukang Chen, Xiaoqing Ye +1

Category-level 6D pose estimation aims to predict the poses and sizes of unseen objects from a specific category. Thanks to prior deformation, which explicitly adapts a category-sp…

Spatial Pruned Sparse Convolution for Efficient 3D Object Detection

Jianhui Liu, Yukang Chen, Xiaoqing Ye +3

3D scenes are dominated by a large number of background points, which is redundant for the detection task that mainly needs to focus on foreground objects. In this paper, we analyz…
