Let Images Give You More: Point Cloud Cross-Modal Training for Shape Analysis

NeurIPS 2022accept

Although recent point cloud analysis achieves impressive progress, the paradigm of representation learning from single modality gradually meets its bottleneck. In this work, we take a step towards more discriminative 3D point cloud representation using 2D images, which inherently contain richer appe…
