PPFNet: Global Context Aware Local Features for Robust 3D Point Matching

CVPR 2018 Haowen DengTolga BirdalSlobodan Ilic

We present PPFNet - Point Pair Feature NETwork for deeply learning a globally informed 3D local feature descriptor to find correspondences in unorganized point clouds. PPFNet learns local descriptors on pure geometry and is highly aware of the global context, an important cue in deep learning... (read more)
