Implicit-Part Based Context Aggregation for Point Cloud Instance Segmentation

Xiaodong Wu,Ruiping Wang,Xilin Chen,Xiaodong Wu,Ruiping Wang,Xilin Chen

Context information is important for instance segmentation on point clouds. Existing methods either only use local surroundings by stacking multiple convolution layers or use non-local methods to model long-range interactions. However, they usually directly operate on points which is an unstructured and low-level representation and is highly dependent on context. To address this issue, we propose ...
