PU-MFA : Point Cloud Up-sampling via Multi-scale Features Attention. (arXiv:2208.10968v1 [cs.CV])

Recently, research using point clouds has been increasing with the
development of 3D scanner technology. According to this trend, the demand for
high-quality point clouds is increasing, but there is still a problem with the
high cost of obtaining high-quality point clouds. Therefore, with the recent
remarkable development of deep learning, point cloud up-sampling research,
which uses deep learning to generate high-quality point clouds from low-quality
point clouds, is one of the fields attracting considerable attention. This
paper proposes a …
