Parallel Implementation of a Full Hyperspectral Unmixing Chain Using OpenCL.
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing(2017)
摘要
Spectral unmixing is an important task for remotely sensed hyperspectral data exploitation. Due to the fact that the spatial resolution of the sensor may not be able to separate different spectrally pure components (endmembers), spectral unmixing faces important challenges in order to characterize mixed pixels. As a result, several hyperspectral unmixing chains have been proposed to find the spect...
