Employing Offset-Attention for 3D Few-shot Semantic Segmentation
Lujun Zhang, Shoukun Xu, Yi Liu · 2022
The existing deep 3D semantic segmentation methods mostly are trained with a large number of human annotations. However, due to the expensive labor for annotations label, few-shot 3D semantic segmentation is achieving more attention. In this work, we improve the performance of few-shot learning based on semantic segmentation of 3D point clouds using the offset attention method that has been successfully applied in natural language processing. Experiments demonstrate the superiority of the offset-attention in 3D semantic segmentation on the benchmark datasets S3DIS.
