Chapter Summary
The main objective of data fusion is use a set of datasets to obtain information
of greater quality than what could be obtained by each single data considered
separately. It is a formal framework in which are expressed means and tools
for the alliance of data originating from different sources. It aims at obtaining
information of greater quality; the exact definition of 'greater quality' will
depend upon the application. Several fusion cases studies were discussed in
this chapter to illustrate the potential of data fusion techniques. The increasing
complexity of the examples is designed to gradually help students understand
data fusion. The diversity of data fusion is so important that the few examples
provided cannot fully describe its complexity. This field is still a strong and
active research in urban remote sensing and the other civilian domains.
