It is not our intention here to treat toy problems, but rather problems of real life in order to demonstrate the applicability of the concepts developed in Chap. 5. To this end we shall consider pattern recognition of faces. A number of persons, say ten, were photographed and the photographs were digitized, usually with 60 by 60 pixels. The background was processed so as to yield a uniform background. The resulting pictures are then supplied with labels A, B, C,..., to identify the names. As described in Chap. 5 we attribute a vector v k (5.2) to each face with its name, where the components are the grey values of each pixel. In our calculations we used four bits to characterize the grey values.
