| Abstract | Good feature extraction and selection methods are crucial for an adequate performance of remote sensing data classification methods. When data dimensionality is very high, a search strategy should be used to select the set of features that gives the minimum classification error or minimize an alternate cheaper criterion related to the classification error. In this paper different search strategies are compared for the case where a region classifier is used. Landsat imagery is first segmented using standard region growing technique. Afterwards a large number of features are extracted from regions, and a smaller set of features is selected by means of three types of search strategy. The set of features selected by each criterion is classified based on minimum Mahalanobis distance and classification accuracy is calculated. As there is no deterministic relation between standard feature selection methods and classification error, is possible to conclude that all search strategies should be used to narrow the number of choices assessments and taking the final decision based on classification error. | |||
