Abstract: Abstract Amphibole phenocrysts and crystal clots composed of amphibole, plagioclase, and interstitial glass were observed in dacitic products of the Unzen 1991–1995 eruption and analyzed in order to understand pre-eruptive magmatic processes. Amphibole phenocrysts in… read more here.

DOI: 10.1109/tgrs.2022.3150263
Abstract: Spectral unmixing plays a vital role in hyperspectral image analysis. It mainly consists of two procedures, i.e., endmember extraction and abundance estimation. Although most algorithms for each of the two procedures may exhibit good performance,… read more here.

DOI: 10.1109/tgrs.2022.3228231
Abstract: An important task of spectral unmixing is to recover the signatures of endmembers from a hyperspectral dataset in which no pure signature is exposed. Most algorithms are based on linear mixing model and require that… read more here.
