Hierarchical video summarisation in reference frame subspace [PDF]
, 2009 In this paper, a hierarchical video structure summarization approach using Laplacian Eigenmap is proposed, where a small set of reference frames is selected from the video sequence to form a reference subspace to measure the dissimilarity between two ...

The Definition and Stability of Local Inertial Reference Frames [PDF]
Symposium - International Astronomical Union, 1990 Inertial reference frames spanning approximately 10°-30° square on the sky and capable of locating objects to few-hundred microarcsecond accuracies are useful for a broad class of astrometric measurements. Deep space tracking and general relativistic angular deflection experiments are examples of astrometric measurements which can profitably reference ...

Point Cloud Registration Based on AGConv Local Feature Descriptors [PDF]
Jisuanji gongcheng, 2023 To improve the registration accuracy of existing point cloud registration models for real point cloud data, an improved point cloud registration model is proposed based on the local feature descriptors of Adaptive Graph Convolution(AGConv).

Locally inertial reference frames in Lorentzian and Riemann‐Cartan spacetimes [PDF]
Annalen der Physik, 2012 AbstractIn this paper the concept of locally inertial reference frames (LIRFs) in Lorentzian and Riemann‐Cartan spacetime structures is scrutinized. A rigorous mathematical definition of a LIRF in both structures is given, something that needs preliminary a clear mathematical distinction between the concepts of observers, reference frames, naturally ...

Dynamic modeling and stability analysis of power networks using dq0 transformations with a unified reference frame; pp. 368–377 [PDF]
Proceedings of the Estonian Academy of Sciences, 2018 The dq0 reference frame has become popular for modeling and control of traditional electric machines and small power sources. However, its widespread use for modeling and analysis of large-scale, general power systems is still a pending issue.

Spacetime Quantum Reference Frames and superpositions of proper times [PDF]
Quantum, 2021 In general relativity, the description of spacetime relies on idealised rods and clocks, which identify a reference frame. In any concrete scenario, reference frames are associated to physical systems, which are ultimately quantum in nature.

Local Alignment of Frame of Reference Assignment in English and Swedish Dialogue [PDF]
, 2020 In this paper we examine how people assign, interpret, negotiate and repair the frame of reference (FoR) in online text-based dialogues discussing spatial scenes in English and Swedish. We describe our corpus and data collection which involves a coordination experiment in which dyadic dialogue participants have to identify differences in their picture ...

GPS-derived ground deformation (2005–2014) within the Gulf of Mexico region referred to a stable Gulf of Mexico reference frame [PDF]
Natural Hazards and Earth System Sciences, 2016 This study investigates current ground deformation derived from the GPS geodesy infrastructure in the Gulf of Mexico region. The positions and velocity vectors of 161 continuous GPS (CGPS) stations are presented with respect to a newly established local ...
