An Advanced Modified Freeman Chain Code Algorithm for Enhancing Arabic Character Recognition

An important challenge in the process of understanding and analyzing writing in Arabic is the recognition of Arabic characters. This article describes an enhanced algorithm aimed at creating Freeman code based on handwritten Arabic letters. This code takes into consideration all variations of handwritten Arabic characters and offers the shortest code length without losing any character information. To exploit the code produced by our improved algorithm, we evaluated this code using a collection of Arabic characters in different formats to recognize Arabic characters. Additionally, we compared our Freeman code with codes produced in other similar works. As a result, the code we received accurately depicts the Arabic character in all of its forms, including those that were not taken into account by the algorithms in previous articles. Therefore, our creative approach based on Freeman coding represents an important step in the recognition of Arabic characters. Additionally, our approach offers an efficient way of representing and classifying Arabic characters.
