Implementation of the fusion by priority

Implementation of the Fusion by Priority

The implementation of this method within the framework of satellite images fusion, meets the problem (already seen previously) of the calculation of the degree of consensus between two groups.

This degree is used to determine if it is necessary:

to apply a conjunctive fusion to the possibility distributions of each group in the event of agreement, or
to discard from fusion the least reliable group and to store only the information of the most reliable group in the event of disagreement.

A calculation of the degree of consensus local to each pixel x, and global for all the classes is performed:

$\begin{displaymath}h(\pi_{K_1}(x), \pi_{K_2}(x)) = \max_{c=1,p}(\min(\pi_{K_1}(x), \pi_{K_2}(x)))\end{displaymath}$

(75)

There is still to determine which are, among all the available sources, those which are most reliable and those which are less.
