Data fusion : a conceptual approach for an efficient exploitation of remote sensing images
Résumé
The need for a definition of the concept of data fusion is established. Already published definitions are discussed. A new definition of the data fusion is proposed, which allows to set up a conceptual approach to the fusion of Earth observation data by putting an emphasis on the framework and on the fundamentals in remote sensing underlying data fusion. Further definitions are given which describe the information intervening in any problem of data fusion. Finally the property of alignment of the information to be fused is discussed.
