The LRF is a coordinate system used to compute local feature descriptors to describe the directional and rotational properties of the local region around a keypoint. Before computing the local feature descriptors, it is necessary to determine the LRF for each key point. Once the orientation of th...

Note that in contrast to prior work, we compute the IoU wrt. the high- resolution mesh and not a coarse voxel representation. All methods apart from AtlasNet [26] are evaluated on the test split by Choy et al. [9]. Since AtlasNet uses a pretrained model,...
