Abstract
In a process for the classification of an article such as a banknote described by of a k-dimensional feature vector (AGF) which is prepared by a preliminary processing system (7), a test specimen is either assigned to one of n target classes or classified as a counterfeit. For the n target classes n recognition units (15.1 to 15.n) are used, exactly one of the n target classes being recognisable by one recognition unit (15.j) using a respective feature vector (AGFj) prepared for that class. A recognised target class is transmitted by an output unit (14) to a service system (11). There are assigned to a target class in a learning phase several k-dimensional target vectors which are compared with the feature vector during the classification. The recognition unit (15.j) is advantageously a neural network, one neuron comparing the feature vector (AGFj) with one of the target vectors.
