摘要: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: apreparatory stage, page segmentation, thinning, baseline estimation, and slanting correction. In thepreparatory stage, the text image is converted via VDs into a group of geometrical forms that consist ofedges and vertices that are used to create the other stages of the proposed model. This stage consists offour main processes: binarization, edge extraction and contour tracking, sampling, and point-VDconstruction. The second stage is the page segmentation stage based on the VD area. In the third stage, anefficient method for text structuring (that is, thinning) is presented. In the fourth stage, a novel baselinebased VD method is presented. In the fifth stage, an efficient technique for slanting detection andcorrection is proposed and discussed.
