АннотацияThe performance of the spectral classifi cation methods is analyzed for the problem of hyperspectral remote sensing of soil and vegetation. The characteristic features of metric classifi ers, parametric Bayesian classifi ers and multiclass support vector machines are discussed. The results of classifi cation of hyperspectral airborne images by using the specifi ed above methods and comparative analysis are demonstrated. The advantages of the use of nonlinear classifi ers are shown. It is also shown, the similarity of the results of some modifi cations of support vector machines and Bayesian classifi cation.
