CoIn: Contrastive Instance Feature Mining for Outdoor 3D Object Detection with Very Limited Annotations

1 code implementation • ICCV 2023 • Qiming Xia, Jinhao Deng, Chenglu Wen, Hai Wu, Shaoshuai Shi, Xin Li, Cheng Wang

Combining CoIn with an iterative training strategy, we propose a CoIn++ pipeline, which requires only 2% annotations in the KITTI dataset to achieve performance comparable to the fully supervised methods.
