* Abstract - The behaviour of two-grid coupled Cellular Neural Networks (CNN's) able to exhibit Turing patterns is investigated for initial conditions representing human faces. Preliminary results based on filtering with various positions and widths of the band of unstable modes are presented. Experiments indicate that Turing-faces may represent a useful pre-processing technique that may increase the performance of traditional PCA-based face recognition approaches.
