Using contextual in formation to improve land use classification of satellite images in central Spain
1991
González-Alonso, F. | López Soria, Salvador
The classification accuracy obtained from the classification of satellite images using pixel-by-pixel conventional methods can be improved if the contextual information is considered jointly with the spectral information in the same strategy of classification. A computer program has been developed to implement a contextual classifier algorithm. The accuracy improvement was evaluated and tested in two pilot zones of central Spain. Two indices were defined in order to analyse the homogeneity effect produced by the contextual classifier. © 1991 Taylor & Francis Ltd.
