Max Daniels, Tyler Maunu, Paul Hand. We consider the fundamental problem of sampling the optimal transport coupling between given source and target distributions. In certain cases, the optimal transport plan takes the form of a one-to-one mapping from the source …

http://staff.ustc.edu.cn/~welbeckz/source/DUP_Net.pdf Web27 Jul 2024 · Figure 1: An overview of our method. The denoising network takes noisy point clouds as input, and then samples a subset of points with low noise via a differentiable pooling layer. Afterwards, manifolds are reconstructed based on the sampled subset of points. Finally, by sampling on the reconstructed manifold, we obtain denoised point …
Web16 Apr 2024 · The results demonstrate unsupervised denoising performance similar to that of supervised learning with clean data when given enough training examples - whereby the student does not need any pairs of noisy and clean training data. We show that denoising of 3D point clouds can be learned unsupervised, directly from noisy 3D point cloud data only. … WebScore-based denoising tend to over-thinning the input point cloud. RePCD-Net [29] introduced a bi-directional RNN based multi-scale feature aggregation module to extract features for different denoising stages and exploited the deep features across denoising recursion stages via recurrent propagation layer.
