WebThe proposed SPA method can register two point clouds effectively using only a small subset of salient points. It first applies the PointHop++ method to point clouds, finds corresponding salient points in two point clouds based on the local surface characteristics of points and performs registration by matching the corresponding salient points. WebIn this work, we improve the PointHop method furthermore in two aspects: 1) reducing its model complexity in terms of the model parameter number and 2) ordering discriminant …

WebPointHop and PointHop++ consist of two modules: 1) unsupervised feature extraction and 2) supervised learning for classification. The proposed R-PointHop method will leverage the first module for the registration task. Another closely related work is the salient points analysis (SPA) method [26]. WebJul 30, 2024 · An explainable machine learning method for point cloud classification, called the PointHop method, is proposed in this work. The PointHop method consists of two stages: 1) local-to-global attribute building through iterative one-hop information exchange and 2) classification and ensembles.
