Decision fusion with reliabilities in multisource data classification
Byeungwoo Jeon, D. A. Landgrebe · 2003
A new multisource classifier based on a fusion of the class decisions of each separate data set is proposed. Each data set is separately fed into the local classifier and a final classification is performed by summarizing these local class decisions. An optimum decision fusion rule based on the minimum expected cost is derived. This new decision fusion rule can handle not only data set reliabilities but also classwise reliabilities of each data set. Classification experiments with two remotely sensed Thematic Mapper data sets showed promising improvement over conventional multisource classification algorithms.>
