Pattern Recognition Scheme for Large-Scale Cloud Detection over Landmarks

no code implementations8 Dec 2020 Adrián Pérez-Suay, Julia Amorós-López, Luis Gómez-Chova, Jordi Muñoz-Marí, Dieter Just, Gustau Camps-Valls

Landmark recognition and matching is a critical step in many Image Navigation and Registration (INR) models for geostationary satellite services, as well as to maintain the geometric quality assessment (GQA) in the instrument data processing chain of Earth observation satellites.

Randomized RX for target detection

no code implementations8 Dec 2020 Fatih Nar, Adrián Pérez-Suay, José Antonio Padrón, Gustau Camps-Valls

This work tackles the target detection problem through the well-known global RX method.

Nonlinear Cook distance for Anomalous Change Detection

no code implementations8 Dec 2020 José A. Padrón Hidalgo, Adrián Pérez-Suay, Fatih Nar, Gustau Camps-Valls

In this work we propose a method to find anomalous changes in remote sensing images based on the chronochrome approach.

Randomized kernels for large scale Earth observation applications

no code implementations7 Dec 2020 Adrián Pérez-Suay, Julia Amorós-López, Luis Gómez-Chova, Valero Laparra, Jordi Muñoz-Marí, Gustau Camps-Valls

Dealing with land cover classification of the new image sources has also turned to be a complex problem requiring large amount of memory and processing time.

Nonlinear Distribution Regression for Remote Sensing Applications

no code implementations7 Dec 2020 Jose E. Adsuara, Adrián Pérez-Suay, Jordi Muñoz-Marí, Anna Mateo-Sanchis, Maria Piles, Gustau Camps-Valls

When the target variable is available at a resolution that matches the remote sensing observations, standard algorithms such as neural networks, random forests or Gaussian processes are readily available to relate the two.

Efficient Nonlinear RX Anomaly Detectors

no code implementations7 Dec 2020 José A. Padrón Hidalgo, Adrián Pérez-Suay, Fatih Nar, Gustau Camps-Valls

In this letter, we propose two families of techniques to improve the efficiency of the standard kernel Reed-Xiaoli (RX) method for anomaly detection by approximating the kernel function with either {\em data-independent} random Fourier features or {\em data-dependent} basis with the Nystr\"om approach.

Fair Kernel Learning

no code implementations16 Oct 2017 Adrián Pérez-Suay, Valero Laparra, Gonzalo Mateo-García, Jordi Muñoz-Marí, Luis Gómez-Chova, Gustau Camps-Valls

It has been shown that not including sensitive features that bias fairness, such as gender or race, is not enough to mitigate the discrimination when other related features are included.
