Point Cloud Denoising via Moving RPCA
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present an algorithm for the restoration of noisy point cloud data, termed Moving Robust Principal Components Analysis (MRPCA). We model the point cloud as a collection of overlapping two‐dimensional subspaces, and ...
Noise Reduction on G‐Buffers for Monte Carlo Filtering
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
We propose a novel pre‐filtering method that reduces the noise introduced by depth‐of‐field and motion blur effects in geometric buffers (G‐buffers) such as texture, normal and depth images. Our pre‐filtering uses world ...
