In this article, we provide an efficient technique that aimed to recognize handwritten characters in real-time by first smoothing the noise components in the text and then extract shape-based invariant features from the handwritten strokes. In real-time handwritten character recognition systems, the challenging factors that constraints the system depends on the stroke noise, geometric behavior (like rotation, scaling and shifting, etc.) of the text. Due to the cursive nature of the Pashto script along with variations in character strokes, the printed, as well as handwritten characters, are difficult to be detected, classified or recognized. Native speakers of the Pashto language are large in numbers and reside in different regions of the world. A set of diacritical marks developed in the 8th century ce are sometimes used to represent short vowels and certain grammatical endings otherwise left unmarked.Pashto scripts are cursive in nature and hard to recognize in real-time.

The shape of each letter depends on its position in a word-initial, medial, and final. It is descended ultimately from the North Semitic alphabet, like its contemporary Aramaic and Greek scripts, but was adapted to fit the broader phonology of the Arabic language and to a cursive style well suited for writing with pen and paper. Others believe that this epigraph shows characteristics of Arabic but is essentially Aramaic and that the earliest extant example of Arabic is a trilingual inscription in Greek, Syriac, and Arabic dating from 512 ce.Ĭlick Here to see full-size table The Arabic alphabet has 28 letters, all representing consonants, and is written from right to left. Some scholars believe that the earliest extant example of Arabic script is a royal funerary inscription of the Nabataeans dating from 328 ce. Although it probably developed in the 4th century ce as a direct descendant of the Nabataean alphabet, its origins and early history are vague. Originally developed for writing the Arabic language and carried across much of the Eastern Hemisphere by the spread of Islam, the Arabic script has been adapted to such diverse languages as Persian, Turkish, Spanish, and Swahili.
