Aesthetical Attributes for Segmenting Arabic Word

The connected allograph representing calligraphic Arabic word does not appear individually in any calligraphic resource but in association with other letters all adapted to each other. The graphic segmentation of the word by respecting aesthetical attributes indicating the grapheme of every letter is far from being an obvious task. The question consists in discovering every letter constituting the word, points of cutting which separate its grapheme from other constituents of word's shape. The obtained segment must be a complete drawing of the represented letter. This segmentation according to contextual graphic and qualitative criteria connecting the attached allograph will have to satisfy typographic constraints varying in conformity with the possibilities offered by the wanted technology. In this paper, we develop an approach for segmenting Arabic word from which the purpose is to extract graphemes respecting the design of Arabic letters such as it is in the calligraphic literature. The procedure bases itself on the principle that the Arabic connected letters have a common part included in the cursive area, which must not be lost during the process of cutting.

Problem of Multiple Diacritics Design for Arabic Script

This study focuses on the design of multiple Arabic diacritical marks and to developing a model that generates the stacking of multiples Arabic diacritics in order to integrate it into a system of Arabic composition. The problem concerns the presence of multiple diacritics on a single basic letter. This model is based on the layering composition. The combination of diacritics with letters requires a basic layering to combine any diacritics in the word with their base letter, without having to deal individually and separately each pair of base letter and diacritics.

Design of Arabic Diacritical Marks

Diacritical marks play a crucial role in meeting the criteria of usability of typographic text, such as: homogeneity, clarity and legibility. To change the diacritic of a letter in a word could completely change its semantic. The situation is very complicated with multilingual text. Indeed, the problem of design becomes more difficult by the presence of diacritics that come from various scripts; they are used for different purposes, and are controlled by various typographic rules. It is quite challenging to adapt rules from one script to another. This paper aims to study the placement and sizing of diacritical marks in Arabic script, with a comparison with the Latin's case. The Arabic script is cursive and runs from right-to-left; its criteria and rules are quite distinct from those of the Latin script. In the beginning, we compare the difficulty of processing diacritics in both scripts. After, we will study the limits of Latin resolution strategies when applied to Arabic. At the end, we propose an approach to resolve the problem for positioning and resizing diacritics. This strategy includes creating an Arabic font, designed in OpenType format, along with suitable justification in TEX.
