Symmetry perception: a novel approach for biological shapes

  title={Symmetry perception: a novel approach for biological shapes},
  author={Hugh R. Wilson and Frances Wilkinson},
  journal={Vision Research},
The majority of quantitative studies on symmetry perception have employed random dot patterns, yet symmetrical random patterns are not common in nature. Here we explore symmetry perception utilizing sums of radial frequency (RF) patterns to define complex shapes. When a pair of RF patterns with different frequencies are added, the relative phase of the two components provides a precise measure of the degree of deviation from bilateral symmetry. Sums of RF2-RF7 define such diverse biological… CONTINUE READING
