Point Contrastive Prediction with Semantic Clustering for Self-Supervised Learning on Point Cloud Videos

no code implementations ICCV 2023 Xiaoxiao Sheng, Zhiqiang Shen, Gang Xiao, Longguang Wang, Yulan Guo, Hehe Fan

Instead of contrasting the representations of clips or frames, in this paper, we propose a unified self-supervised framework by conducting contrastive learning at the point level.
