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...

When using such a network for 3D reconstruction of an object based on observations of that object (e.g., image, point cloud, etc.), we must condition it on the input. Fortu- nately, we can make use of the following simple functional equivalence: a functi...
