Filling missing data and smoothing altered data in satellite imagery with a spatial functional procedure
Militino, Ana F. ; Ugarte Martínez, María Dolores ; Montesino San Martín, Manuel (Springer, 2019)
Artículo / Artikulua
Outliers and missing data are commonly found in satellite imagery. These are usually caused by atmospheric or electronic failures, hampering the correct monitoring of remote-sensing data. To avoid distorted data, we propose ... -
Flexible Bayesian P-splines for smoothing age-specific spatio-temporal mortality patterns
Goicoa Mangado, Tomás; Adin Urtasun, Aritz ; Etxeberria Andueza, Jaione ; Militino, Ana F. ; Ugarte Martínez, María Dolores (SAGE, 2019)
Artículo / Artikulua
In this paper age-space-time models based on one and two-dimensional P-splines with B-spline bases are proposed for smoothing mortality rates, where both xed relative scale and scale invariant two-dimensional penalties ... -
Improving the quality of satellite imagery based on ground-truth data from rain gauge stations
Militino, Ana F. ; Ugarte Martínez, María Dolores ; Pérez Goya, Unai (MDPI, 2018)
Artículo / Artikulua
Multitemporal imagery is by and large geometrically and radiometrically accurate, but the residual noise arising from removal clouds and other atmospheric and electronic effects can produce outliers that must be mitigated ... -
Interpolation of the mean anomalies for cloud filling in land surface temperature and normalized difference vegetation index
Militino, Ana F. ; Ugarte Martínez, María Dolores ; Pérez Goya, Unai ; Genton, Marc G. (IEEE, 2019)
Artículo / Artikulua
When monitoring time series of remote sensing data, it is advisable to fill gaps, i.e., missing or distorted data, caused by atmospheric effects or technical failures. In this paper, a new method for filling these gaps ... -
An introduction to the spatio-temporal analysis of satellite remote sensing data for geostatisticians
Militino, Ana F. ; Ugarte Martínez, María Dolores ; Pérez Goya, Unai (Springer International Publishing, 2018)
Capítulo de libro / Liburuen kapitulua
Satellite remote sensing data have become available in meteorology, agriculture, forestry, geology, regional planning, hydrology or natural environment sciences since several decades ago, because satellites provide routinely ... -
Locally adaptive change-point detection (LACPD) with applications to environmental changes
Moradi, Mohammad Mehdi ; Montesino San Martín, Manuel ; Ugarte Martínez, María Dolores ; Militino, Ana F. (Springer, 2021)
Artículo / Artikulua
We propose an adaptive-sliding-window approach (LACPD) for the problem of change-point detection in a set of time-ordered observations. The proposed method is combined with sub-sampling techniques to compensate for the ... -
