Zusammenfassende Darstellung der Ergebnisse, optimisation-based band selection approaches are discussed using genetic algorithms (GAs) and particle swam optimisation (PSO). In contrast to exhaustive search algorithms, optimisation-based approach employs fast search measures to find a better solution in a large solution space. The key strength

However, in reality, it is difficult to perceive the required number of bands before the analysis starts. A particular number of (selected or extracted) fe

The authors first explain how hyperspectral imagery (HSI) plays an important role in remote sensing due to its high spectral resolution that enables better identification of different materials on?the earth’s?surface. The authors go on to describe potential challenges due to HSI being acquired in

Finally, the selected bands are classified, and overall accuracy (OA) is calculated. This method is compared with four other existing state-of-the-art methods in the similar field in terms of OA and execution time for evaluating the performance.
