基于模式的二维离散沃尔什变换和信息论中的熵概念，提出了一种新的单模式对称性的客观度量--对称性。它被扩展到一个更一般的措施，称为对称向量。为了测试对称向量的预测能力，对判断模式的良好性和判断模式的复杂性进行了多元回归分析。对称性向量预测模式的良好性和模式的复杂性，以及模式中的对称性。模式优良性可以是基于模式的整体属性的概念，而模式复杂性（或简单性）可以是基于模式的整体和部分属性的概念。
A new objective measure of symmetry for single patterns, called symmetropy, is developed on 2 bases, the 2-dimensional discrete Walsh transform of a pattern and the entropy concept in information theory. It is extended to a more general measure, called the symmetropy vector. To test the predictive power of the symmetropy vector [in humans], multiple regression analyses of judged pattern goodness and of judged pattern complexity were carried out. The symmetropy vector predicted pattern goodness and pattern complexity, as well as the amount of symmetry in a pattern. Pattern goodness may be a concept based on the holistic properties of a pattern, while pattern complexity (or simplicity) may be a concept based on holistic and partial properties of a pattern.
