Consistent ICP for the registration of sparse and inhomogeneous point clouds [PDF]

open access: yes, 2016
In this paper, we derive a novel iterative closest point (ICP) technique that performs point cloud alignment in a robust and consistent way. Traditional ICP techniques minimize the point-to-point distances, which are successful when point clouds contain ...

Orienting point clouds with dipole propagation [PDF]

open access: yesACM Transactions on Graphics, 2021
Establishing a consistent normal orientation for point clouds is a notoriously difficult problem in geometry processing, requiring attention to both local and global shape characteristics. The normal direction of a point is a function of the local surface neighborhood;

Determinação do ponto de névoa em surfactantes não iônicos por espectroscopia de impedância elétrica

open access: yesQuímica Nova, 2010
In this paper, we analyze the use of electrical impedance spectroscopy applied to determination of cloud point. The slope of admittance measured at 100 kHz is reduced to temperature above the critical value which characterizes the phase transition, in a ...

Cold fl ow properties of palm oil biodiesel

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
The faulty performance of palm oil biodiesel at low temperatures constitutes its main quality drawback and limitation to use this alternative fuel for diesel engines either as a neat fuel or blended with conventional diesel fuel derived from petroleum ...

Self-Ordering Point Clouds

open access: yes2023 IEEE/CVF International Conference on Computer Vision (ICCV), 2023
In this paper we address the task of finding representative subsets of points in a 3D point cloud by means of a point-wise ordering. Only a few works have tried to address this challenging vision problem, all with the help of hard to obtain point and cloud labels.

Cloud Base Signature in Transmission Spectra of Exoplanet Atmospheres [PDF]

open access: yes, 2014
We present an analytical model for the transmission spectrum of a transiting exoplanet, showing that a cloud base can produce an observable inflection point in the spectrum.

Point clouds in BIM [PDF]

open access: yesIOP Conference Series: Earth and Environmental Science, 2016
The representation of physical buildings in Building Information Models (BIM) has been a subject of research since four decades in the fields of Construction Informatics and GeoInformatics. The early digital representations of buildings mainly appeared as 3D drawings constructed by CAD software, and the 3D representation of the buildings was only ...
