Recognition of Off-Line Handwritten Arabic Words Using Hidden Markov Model Approach
نویسندگان
چکیده
Hidden Markov Models (HMM) have been used with some success in recognizing printed Arabic words. In this paper, a complete scheme for totally unconstrained Arabic handwritten word recognition based on a Model discriminant HMM is presented. A complete system able to classify Arabic-Handwritten words of one hundred different writers is proposed and discussed. The system first attempts to remove some of variation in the images that do not affect the identity of the handwritten word. Next, the system codes the skeleton and edge of the word so that feature information about the lines in the skeleton is extracted. Then a classification process based on the HMM approach is used. The output is a word in the dictionary. A detaiedl experiment is carried out and successful recognition results are reported.

متن کاملRecognising handwritten Arabic manuscripts using a single hidden Markov model
This paper presents a new method on off-line recognition of handwritten Arabic script. The method does not require segmentation into characters, and is applied to cursive Arabic script, where ligatures, overlaps and style variation pose challenges to the recognition system. The method trains a single hidden Markov model (HMM) with the structural features extracted from the manuscript words. The...
متن کاملHolistic Farsi handwritten word recognition using gradient features
In this paper we address the issue of recognizing Farsi handwritten words. Two types of gradient features are extracted from a sliding vertical stripe which sweeps across a word image. These are directional and intensity gradient features. The feature vector extracted from each stripe is then coded using the Self Organizing Map (SOM). In this method each word is modeled using the discrete Hidde...

This paper describes a technique for the recognition of off-line handwritten Arabic (Indian) numerals using Radon-Fourier-based features. A two stage classification scheme is used. The Nearest Mean (NMC), K-Nearest Neighbor (K-NNC), and Hidden Markov Models (HMMC) Classifiers are used in the first stage and a Structural Classifier (SC) is used in the second stage. A database of 44 writers with ...

This paper presents a recognition system for Arabic handwritten isolated characters. The recognition system is based on hidden Markov model (HMM). The entire system is capable of recognizing the Arabic handwritten characters. First, the system removes all the variation in the character images. Second, Features are extracted using the sliding window technique with HMM. Then, the HMM is used for ...
