Assessing the Performance-Energy Balance of Graphics Processors for Spectral Unmixing
Sánchez, S.; León Navarro, Germán; Plaza, Antonio; Quintana-Orti, Enrique S. IEEE (2014)Remotely sensed hyperspectral imaging missions are often limited by onboard power restrictions while, simultaneously, require high computing power in order to address applications with relevant constraints in terms of ... -
Efficient Implementation of Hyperspectral Anomaly Detection Techniques on GPUs and Multicore Processors
Molero, Jose M.; Garzon, E.M.; García, I.; Quintana-Orti, Enrique S.; Plaza, Antonio IEEE (2014)Anomaly detection is an important task for hyperspectral data exploitation. Although many algorithms have been developed for this purpose in recent years, due to the large dimensionality of hyperspectral image data, fast ... -
Exploring the performance–power–energy balance of low-power multicore and manycore architectures for anomaly detection in remote sensing
León Navarro, Germán; Molero, Jose M.; Garzon, E.M.; García, I.; Plaza, Antonio; Quintana-Orti, Enrique S. Springer Verlag (2015)In this paper, we perform an experimental study of the interactions between execution time (i.e., performance), power, and energy that occur in modern low-power architectures when executing the RX algorithm for detecting ... -
Fast and Reliable Noise Estimation for Hyperspectral Subspace Identification
Benner, Peter; Novaković, Vedran; Plaza, Antonio; Quintana-Orti, Enrique S. Institute of Electrical and Electronics Engineers (IEEE) (2015-02)In this letter, we introduce an efficient algorithm to estimate the noise correlation matrix in the initial stage of the hyperspectral signal identification by minimum error (HySime) method, commonly used for signal subspace ... -
Hyperspectral Unmixing on Multicore DSPs: Trading Off Performance for Energy
Castillo Catalán, María Isabel; Fernández Fernández, Juan Carlos; Igual, Francisco; Plaza, Antonio; Quintana-Orti, Enrique S.; Remón Gómez, Alfredo IEEE (2014)Wider coverage of observation missions will increase onboard power restrictions while, at the same time, pose higher demands from the perspective of processing time, thus asking for the exploration of novel high-performance ... -
Performance versus energy consumption of hyperspectral unmixing algorithms on multi-core platforms
Remón Gómez, Alfredo; Sánchez, Sergio; Bernabé, Sergio; Quintana-Orti, Enrique S.; Plaza, Antonio SpringerOpen (2013)Hyperspectral imaging is a growing area in remote sensing in which an imaging spectrometer collects hundreds of images (at different wavelength channels) for the same area on the surface of the Earth. Hyperspectral images ... -
Real-time endmember extraction on multicore processors
Quintana-Orti, Enrique S.; Remón Gómez, Alfredo; Sánchez, Sergio; Paz, Abel; Plaza, Antonio IEEE (2011)In this letter, we discuss the use of multicore processors in the acceleration of endmember extraction algorithms for hyperspectral image unmixing. Specifically, we develop computationally efficient versions of two popular ...
