Abstract

Shape descriptors play an important role in many document analysis application. In this paper we review some of the shape descriptors proposed in the last years from a new point of view. We propose the definitions of descriptor and primitive and introduce the notion of feature extraction method. With these definitions, we propose a new classification of shape descriptors that permits to classify according to their properties pointing out their strengths and weaknesses.
用于文献分析的形状描述符综述
形状描述符在许多文档分析应用中起着重要的作用。本文从一个新的角度回顾了近年来提出的一些形状描述子。提出了描述符和原语的定义,并引入了特征提取方法的概念。根据这些定义,我们提出了一种新的形状描述符分类,允许根据它们的属性进行分类,指出它们的优缺点。
