一、Few-shot点云语义分割和传统3D点云语义分割的主要区别在于数据量和训练策略: 数据量: 传统3D点云语义分割通常需要大量的标记数据,以便训练深度学习模型,使其能够准确地理解和分割各种类别。这意味着对于每个类别,都需要有足够数量的已标记点云示例。 Few-shot点云语义分割则在训练时使用极少量的已标记示例,通常...
Few-Shot Point Cloud Semantic Segmentation via Contrastive Self-Supervision and Multi-Resolution Attention 2023 ICRA 出发点:完全监督学习的预训练导致有偏见的特征提取,对泛化有害,且严重依赖于大规模的注释数据集 解决方案:采用对比自监督技术进行预训练提取更通用的特征,有效消除对注释数据集的依赖;只关注局部最近...
2|1(1) Point Cloud Representation 文章中点云表示是一种独特的基于体素的“微型点网”,它有两个步骤:体素化(Voxelization)和mini-PointNet构造。 体素化(Voxelization):给定范围在Lx × Ly × Lz内的点云P作为输入,将不规则的点转移到分辨率为H×W×D的规则三维体素中。分辨率由体素参数S=(Sx, Sy, Sz)(...
