Generation of Sub-Pixel-Level Maps for Mixed Pixels in Hyperspectral Image Data

open access: yesCurrent Science, 2021
Hyperspectral data can find wide applications in classification and mapping of pure and mixed pixels in images of different land-cover types. Hyperspectral data of high spectral resolution enhance discrimination of target objects; but the low spatial resolution poses a challenge due to creation of mixed pixels.
