CloudWalker: Random walks for 3D point cloud shape analysis

Abstract

Figure 1. CloudWalker's pipeline. A set of random walks is generated for a given point cloud. Each walk explores the object on its path (points on the walk are color-coded according to their position in the walk sequence, from blue to yellow). We use CloudWalker for two tasks: 3D object retrieval and classification and achieve state of the art results.
