Figure 2.23 presents an example for a honing texture. Figure 2.23a depicts the original image and Figure 2.23b presents an artificially generated texture based on an estimated AR model of order 84. The AR model is a rather generic model that does not make use of any context specific knowledge. The question of what order the AR model should have cannot be answered in general. Usually one has to resort to some trial-and-error approach until the achieved result is acceptable. Generally this leads to an unnecessary high dimension of the parameter space. Furthermore, the AR coefficients do not have an easily interpretable meaning in terms of the modelled pattern.
