Handwriting Arabic character recognition using haar wavelet compression

The typical optical character recognition (OCR) systems, regardless the characterpsilas nature, are based mainly on three stages, preprocessing, features extraction and discrimination (recognizer). Each stage has its own problems and effects on the system efficiency such as time consuming and recognition errors. In order to avoid these difficulties this research paper presents new construction of OCR system for handwriting Arabic characters using a technique similar to that is used in wavelet compression. The proposed algorithm obtained promising results in terms of accuracy (reaches 97.9% for some letters at average 80%) as well as in terms of time consuming.
