Learning without Forgetting for 3D Point Cloud Objects

1 code implementation27 Jun 2021 Townim Chowdhury, Mahira Jalisha, Ali Cheraghian, Shafin Rahman

Experimenting on three 3D point cloud recognition backbones (PointNet, DGCNN, and PointConv) and synthetic (ModelNet40, ModelNet10) and real scanned (ScanObjectNN) datasets, we establish new baseline results on learning without forgetting for 3D data.
