PointAtrousGraph: Deep Hierarchical Encoder-Decoder with Point Atrous Convolution for Unorganized 3D Points
Liang Pan, Chee-Meng Chew, Gim Hee Lee
Motivated by the success of encoding multi-scale contextual information for image analysis, we propose our PointAtrousGraph (PAG) - a deep permutation-invariant hierarchical encode…

Edge and Corner Detection for Unorganized 3D Point Clouds with Application to Robotic Welding
Syeda Mariam Ahmed, Yan Zhi Tan, Chee Meng Chew +2
In this paper, we propose novel edge and corner detection algorithms for unorganized point clouds. Our edge detection method evaluates symmetry in a local neighborhood and uses an…
