A Gaussian Process Model for Color Camera Characterization: Assessment in Outdoor Levantine Rock Art Scenes

Molada-Tebar, Adolfo; Riutort-Mayol, Gabriel; Marqués-Mateu, Ángel; Lerma, José Luis (MDPI AG, 2019-11)

[EN] In this paper, we propose a novel approach to undertake the colorimetric camera characterization procedure based on a Gaussian process (GP). GPs are powerful and flexible nonparametric models for multivariate nonlinear ...
A methodology to select particle morpho-chemical characteristics to use in source apportionment of particulate matter from livestock houses

Cambra López, María; Hermosilla Gómez, Txomin; Aarnink, André Johannes Antonius; Ogink, Nico (Elsevier, 2012-02)

[EN] Intensive poultry and pig houses are major point sources of particulate matter (PM) emissions. The knowledge on the contribution of individual sources to PM in different fractions is essential to improve PM reduction ...
A NEW METHODOLOGY FOR THE 3D PHOTOREALISTIC VIRTUAL RECONSTRUCTION OF THE ARCHAEOLOGICAL SITE “CASTELLET DE BERNABÉ” (LLÍRIA, SPAIN)

Portalés Ricart, Cristina; Alonso-Monasterio Fernández, Pau; Viñals Blasco, Mª José (Editorial Universitat Politècnica de València, 2016-10-27)

[EN] In recent decades, the 3D virtual reconstructions and visualizations of archaeological sites have been commonly used by scientists to better understand the missing structures. They have also been considered as an ...
A new methodology to estimate the discrete-return point density on airborne lidar surveys

Balsa Barreiro, José; Lerma García, José Luis (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2014-02)

The distribution of the discrete-return point density in airborne lidar flights obtained from an oscillating mirror laser scanner is analysed and alternative formulations to determine its value are presented. The point ...
