Example text

Let cln be the class returned by the nearest center classifier, cld the one returned by AANNs, and cl the true class. The cell (i,j) of the “relevancy matrix” provides the probability that the classifier returns the true result while the two classifiers respectively select classes i and j: ­ M n (i, j ) = P(cl = cln | i, j ) . ® ¯ M d (i, j ) = P(cl = cld | i, j ) (4) When both classifiers lead to the same result, the decision is evident. Otherwise, when the returned classes are different, the “relevancy matrix” will be used to decide among the two classes, which is the true class.

For the tracking step, works are often based on multiple hypotheses analysis [5], other on statistics [2,3]. We chose to use color and texture combined with some hypotheses analysis to determine new and previous objects in the scene. That is, we track by appearance. Finally for the third step, we focus on tracking object relationships regardless of their identity. This will allow us analyzing specific behaviors of the detected objects such as the transportation of objects [2], or an illegal entry in a forbidden area [6].

8 32 A. Mokhber et al. Table 4. 1 6 Association of Classifiers Results presented in the two previous sections show that classifiers do not have the same behavior. It often appears that if one classifier is wrong, the other one selects the true result. Therefore, it would be of interest to identify the cases where one classifier has to be preferred over the other, especially when the outcomes of the two classifiers are different. Thus, for each classifier, a “relevancy matrix” is constructed based on the training database.
