A software application for automatic descriptive feature extraction from image-objects, FETEX 2.0, is presented and described in this paper. The input data include a multispectral high resolution digital image and a vector ...
A full-waveform airborne laser scanning metric extraction tool for forest structure modelling. Do scan angle and radiometric correction matter?

Crespo-Peremarch, Pablo; Ruiz Fernández, Luis Ángel (MDPI AG, 2020-01)

[EN] In the last decade, full-waveform airborne laser scanning (ALSFW) has proven to be a promising tool for forestry applications. Compared to traditional discrete airborne laser scanning (ALSD), it is capable of registering ...
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 ...
