“…Forming an MLN would often require estimation of distances among nodes and can be time-consuming. Fortunately, we can bypass such complexity and estimate MLN spectrum directly from datasets based on signal properties, e.g., smoothness or stationarity [27]- [30]. In this part, we mainly focus on two scenarios:…”

“…As a new form of 3D signal expression, point cloud has received widespread attention due to the talent for representing 3D shapes efficiently and being obtained directly and easily by scanning. And it has been adopted in many applications, such as segmentation [1], [2], 3D reconstruction [3], [4], compression [5]- [7], autonomous driving [8]. Particularly, although dense correspondence estimation is a fundamental task in computer vision, which has been investigated widely on other signal formats (e.g.…”

“…Furthermore, by generalizing graph signal processing [19], hypergraph signal processing (HGSP) [21] [20] provides a theoretical foundation for spectral analysis in hypergraph-based point cloud processing. Specifically, stationarity-based hypergraph estimation, in conjunction with hypergraph-based filters, has demonstrated notable successes in processing point clouds for various tasks including segmentation, sampling, and denoising [22], [23].…”
