Recognition of Handwritten Characters by Voronoi Representations Recognition of Handwritten Characters by Voronoi Representations
We present a new skeletonization algorithm well suited for the problem of handprinted character recognition. Our approach employs a novel algorithm for computing the Voronoi diagram of a polygon with holes. We show that Voronoi skeletons can serve as eecient shape descriptors because they preserve connectivity and Euclidean metrics. Compared to traditional skeletonization techniques, we suggest...
متن کاملSegmentation of Arabic Characters: A Comprehensive Survey
The cursive nature of Arabic writing is the main challenge to Arabic Optical Character Recognition developer. Methods to segment Arabic words into characters have been proposed. This paper provides a comprehensive review of the methods proposed by researchers to segment Arabic characters. The segmentation methods are categorized into nine different methods based on techniques used. The advantag...
متن کاملSegmentation and Recognition of Printed Arabic Characters
Arabic characters differ significantly from other characters such as Latin and Chinese characters in that they are written cursively in both printed and handwritten forms and consist of 28 main characters. However most of their shapes change according to their position in the word. These shapes together with some other secondaries raise the number of classes to 120. Furthermore, some of these c...
متن کاملA Preprocessing Model for Hand-written Arabic Texts Based on Voronoi Diagrams
In this paper, a preprocessing model for hand-written Arabic text on the basis of the Voronoi Diagrams (VDs) is presented and discussed. The proposed VD-based pre-processing model consists of five stages: a preparatory stage, page segmentation, thinning, baseline estimation, and slanting correction. In the preparatory stage, the text image is converted via VDs into a group of geometrical forms ...
