Anomaly detection is an important task for hyperspectral data exploitation. A standard approach anomaly in the literature method developed by Reed and Xiaoli, also called RX algorithm. variation of this algorithm consists applying same concept to a local sliding window centered around each image pixel. The computational cost very high it strongly increases its versions. However, current advances performance computing help reduce run-time these algorithms. So, RX, possible achieve processing...
Spectral unmixing is an important technique for hyperspectral data exploitation, in which a mixed spectral signature decomposed into collection of spectrally pure constituent spectra, called endmembers, and set correspondent fractions, or abundances, that indicate the proportion each endmember present mixture. Over last years, several algorithms have been developed automatic semiautomatic extraction. Some available approaches assume input contains at least one distinct material further...
A continuous location problem in which a firm wants to set up two or more new facilities competitive environment is considered. Other offering the same product service already exist area. Both locations and qualities of are be found so as maximize profit obtained by firm. This global optimization problem, with many local optima. In this paper we analyze several approaches solve it, namely, three multistart search heuristics, simulated annealing algorithm, variants an evolutionary algorithm....

Anomaly detection is an important task for hyperspectral data exploitation. A standard approach anomaly in the literature method developed by Reed and Yu, also called RX algorithm. It implements Mahalanobis distance, which has been widely used imaging applications. variation of this algorithm, known as kernel (KRX), consists applying same concept to a sliding window centered around each image pixel. KRX computationally very expensive because, every pixel, covariance matrix its inverse be...
Anomaly detection is an important task for hyperspectral data exploitation. Although many algorithms have been developed this purpose in recent years, due to the large dimensionality of image data, fast anomaly remains a challenging task. In work, we exploit computational power commodity graphics processing units (GPUs) and multicore processors obtain implementations well-known algorithm by Reed Xiaoli (RX algorithm), local (LRX) variant, which basically consists applying same concept...
The focus of this paper is on the analysis and evaluation a type parallel strategies applied to algorithm Advanced Multidimensional Interval Global Optimization (AMIGO). We investigate two versions AMIGO, called Parallel AMIGO (PAMIGO) algorithm, Global-PAMIGO Local-PAMIGO. idea behind our study that in order exploit potential parallelism algorithms, researchers need adapt them target computer architectures. Our PAMIGO algorithms have been designed for shared memory architectures are based...
