Fig. 8.5 (A) In the case of noisy or incomplete input patterns, the system automatically fills in or completes the missing portions of the pattern, while registering the identity of the recognized pattern in the resonator response. (B) In the case of ambiguous patterns, the system becomes multistable between alternative interpretations. (C) Even for simple inputs the system can be multistable when stimulated to higher energies, interpreting the input with any standing wave that contains the input as a subset. This excludes the last pattern on the right. (D) The system is invariant to elastic deformations of the input pattern, as long as the global gestalt is preserved.
