| Abstract: | Wetlands are integral parts of the global ecosystem as they can prevent or reduce the severity of floods,feed ground water,and provide unique habitats for flora and fauna.Wetland remote sensing classification is one of the most important means to realize wetland dynamic monitoring,management and utilization.But spectral uncertainty or vagueness caused by spectral confusion between-class and spectral variation within-class remains a challenge to the wetland remote sensing classification.Exploring small sampl... |
