Zernike矩（ZM）已被成功地应用于形状识别问题。它们的性质允许解决这项任务中的一些基本问题。其中最重要的是旋转、缩放、平移和相对对称的不变性。此外，所获得的表示可以根据形状的概括水平而变化。为此，本文提出并实验研究了将零网格法应用于一般形状分析问题。GSA问题类似于形状的识别和检索。然而，只有最一般的形状类别（例如正方形，三角形，圆形，椭圆形）被假定为执行基本模板的角色。此外，被处理的对象不必属于任何模板类，而可以仅与其中之一相似。这使我们能够接收有关形状的最一般信息，例如，它是正方形，三角形，圆形，椭圆形等。在本文中，为了评估Zernike矩应用于GSA的问题，这个形状描述符的性能进行了比较，提供了近两百人，并通过适当的查询形式收集的结果。
: The Zernike Moments (ZM) have been successfully applied to the problem of shape recognition. Their properties allow for solving some fundamental problems in this task. Amongst them the most important one is the invariance to rotation, scaling, translation, and reflectional symmetry. Moreover, the obtained representation can vary according to the level of generalisation of a shape. For this reason in the paper the application of the ZM to the problem of General Shape Analysis (GSA) is proposed and experimentally investigated. The GSA problem is similar to the recognition and retrieval of shapes. However, only the most general classes of shapes (e.g. square, triangle, circle, ellipse) are assumed to perform the role of the basic templates. Moreover, the processed object does not have to belong to any of the template classes, but may be only similar to one of them. This enables us to receive the most general information about a shape, e.g. how square, triangular, round, elliptical, etc. it is. In the paper, in order to evaluate the Zernike Moments applied to the problem of GSA, the performance of this shape descriptor is compared with the results provided by nearly two hundred humans and collected by means of appropriate inquiry forms.
