Visualization of level-of-detail meshes on the GPU
(Springer Verlag, 2011-09-01)
Extensive research has been carried out in multiresolution
models for many decades. The tendency in recent
years has been to harness the potential of GPUs to
perform the level-of-detail extraction on graphics hardware.
The ...
Efficient visualization of 3D models on hardware-limited portable devices
(Springer, 2014)
Managing the geometry of a 3D scene efficiently is a key aspect of an interactive 3D application. This aspect is more important if we target at portable devices, which have limited hardware capabilities. Developing new ...
The space-bandwidth product in the join ttransform correlator optical encryption setup
(Elsevier, 2011)
In this work we study the joint transform correlator (JTC) optical encryption setup through the Wigner function. We found analytical expressions for the spatial and spatial frequency extent of the encrypted signal. Since ...
Spatial recurrences for pedestrian classification
(Springer U.S., 2012-09)
In this work, a framework is proposed for pedestrian classification based on spatial recurrences in the form of recurrence plots. This representation is more general and potentially more discriminative than a histogram of ...
Frequency Stability Requirements in Quasi-Integer-Ratio Time-Expanded Phase-Sensitive OTDR
(IEEE, 2023-01-15)
Time-expanded phase sensitive (TE-ϕ)OTDR is a recently reported technique for distributed fiber sensing that relies on the use of an electro-optic dual frequency comb (DFC) scheme. A distinctive feature of this approach ...
Hyperspectral remote sensing of foliar nitrogen content
(National Academy of Sciences, 2012)
A strong positive correlation between vegetation canopy bidirectional reflectance factor (BRF) in the near infrared (NIR) spectral
region and foliar mass-based nitrogen concentration (%N) has
been reported in some temperate ...
Managing user-generated information in geospatial cyberinfrastructures
(Elsevier, 2011)
Information systems built using standards-based distributed services have become the default computing paradigm adopted by the geospatial community for building information infrastructures also known as Spatial Data ...
Geostatistical methods to identify and map spatial variations of soil salinity
(Elsevier, 2011-01)
The problem of estimating and predicting spatial distribution of a spatial stochastic process, observed at irregular locations in space, is considered in this paper. Environmental variables usually show spatial dependencies ...
Spatio-temporal stochastic modelling of environmental hazards
(Copyright © 2015 Elsevier, 2015-09)
This is the editorial letter for the Special Issue dedicated to the joint VII International Workshop on Spatio-temporal Modelling (METMAVII) and the 2014 meeting of the research group for Statistical Applications to ...
Unsupervised detection of transitions at home by using BLE technology
(IEEE, 2021-11)
This paper presents a set of unsupervised methods based on Bluetooth Low Energy (BLE) technology to obtain the position and transitions that users perform between the zones where they usually stay longer in their own homes. ...
