متن کاملThe Thinning Problem in Arabic Text Recognition – A Comprehensive Review
The goal of this paper is to present an overview about the thinning problem in Arabic text recognition. Thinning "Skeletonization" is a very crucial stage in the ACR, it simplifies the text shape and reduces the amount of data that needs to be handled and it is usually used as a pre-processing stage for recognition and storage systems.

متن کاملHigh capacity steganography tool for Arabic text using 'Kashida'
Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...
متن کاملArabic Text Recognition System
This paper describes a system for the recognition of Arabic text in document images. The system is designed to perform well on low resolution and low quality document images. On a set of 138 page images digitized at 200x200 dpi the system achieved a 93% correct character recognition rate. On the same pages digitized at 100x200 dpi, the system achieved an 89% character recognition rate. The syst...
متن کاملUtilizing Extension Character 'Kashida' with Pointed Letters for Arabic Text Digital Watermarking
This paper exploits the existence of the redundant Arabic extension character, i.e. Kashida. We propose to use pointed letters in Arabic text with a Kashida to hold the secret bit ‘one’ and the un-pointed letters with a Kashida to hold ‘zero’. The method can be classified under secrecy feature coding methods where it hides secret information bits within the letters benefiting from their inherit...
