Over the last few years, several new strategies for spectral unmixing of remotely sensed hyperspectral data have been proposed. Many of them have been developed to solve the most time-consuming and relevant step: endmember extraction. However, unmixing algorithms can be computationally very expensive in terms of processing time and energy consumption, a fact that compromises their use in applications...
Many algorithms for spectral unmixing have been proposed in the last years applied on hyperspectral imaging. This process is composed by three stages where the extraction of endmembers is the most consuming step. However, endmember extraction algorithms (EEAs) can be computationally very expensive and its acceleration on parallel architectures is still an interesting and open problem. In this paper,...
