Abstract

In order to overcome the deficiencies of traditional uncertainty assessment methods of remote sensing images classification by error-matrix and kappa coefficient, classification uncertainties at pixel scale of Beijing-1 small satellite multi-spectrum remote sensing images were measured and represented. Firstly, an unsupervised classification algorithm-neighborhood EM considering spatial autocorrelation and classification fuzziness-was introduced. Then, four uncertainty assessment indexes of neighborhood EM classification-fuzzy membership residual, relative maximum fuzzy membership deviation, fuzzy membership entropy and relative fuzzy membership entropy - were constructed. Finally, the experiments concerned were performed using Beijing-1 small satellite multi-spectrum remote sensing image data in Dongkunlun, Qinghai province, China.
