WebJul 1, 2024 · A novel 3D descriptor named Histograms of Local Point Pair Features (HoPPF) is proposed. • • Three modules for HoPPF, including data preprocessing, local point pair set division, distribution matrix generation are proposed. • • Accurate recognition results on real datasets validate that the HoPPF can be applied to 3D vision. Abstract WebThe Viewpoint Feature Histogram (or VFH) has its roots in the FPFH descriptor (see Fast Point Feature Histograms (FPFH) descriptors ). Due to its speed and discriminative power, we decided to leverage the strong recognition results of FPFH, but to add in viewpoint variance while retaining invariance to scale.
