Machine printed Farsi/Arabic sub-words retrieval by shape signatures

Abstract

This paper focuses on shape description for machine printed Farsi/Arabic subwords retrieval. Fourier descriptor (FD) has been used frequently for shape retrieval applications. In this paper we proposed a simple and effective FD based technique for subwords retrieval. In this method, the small number of global parameters is used to eliminate dissimilar subwords. To investigate the efficiency of the proposed method, it is compared with six common FD signatures on a database including Farsi subwords of 4 fonts and 3 sizes. Experimental results show that the proposed method outperforms the others.
