Outliers Removal and Consolidation of DYNAMIC Point Cloud

Recently, there has been increasing interest in the processing of dynamic scenes as captured by 3D scanners, ideally suited for challenging applications such as immersive tele-presence systems and gaming. Despite the fact that the resolution and accuracy of the modern 3D scanners are constantly improving, the captured 3D point clouds are usually noisy with a perceptive percentage of outliers, stressing the need of an approach with low computational requirements which will be able to automatically remove the outliers and create a consolidated point cloud. In this paper, we introduce a novel method which first recognizes and removes outliers from a dynamic point cloud sequence (DPCS) using a very fast Robust PCA (RPCA) approach and then we use a novel weighted Laplacian interpolation approach to achieve a fast and effective consolidation of a DPCS. Extensive evaluation studies, carried out using a collection of different DPCS, verify that the proposed technique achieves plausible reconstruction output despite the constraints posed by arbitrarily complex motion scenarios.
