Quantitative analyses were undertaken to obtain a priori information regarding the energy levels of the random-dot display or Moir¨¦ patterns as a function of the angle of rotation θ by employing classical Newtonian mechanics. The energy profiles for these patterns were found to be similar for 10¡ã<θ <350¡ã in which the energies exhibited a maxima. For 10¡ã≥ θ ≥ 350¡ã, the profiles were found to be dramatically different, especially for the focus pattern where the profile exhibited a downward spike. Specifically, it was found that the minimum energy levels correspond to the angles of rotation where the profiles are perceived by humans. These results may provide insights into the underlying mechanism responsible for the perception of these patterns and information processing in the brain, specifically in the cerebral cortex.
