English Abstract

Many methods have been reported for handwriting-based writer identification.

None of these methods assumes that this technique is possible in Arabic.

In this dissertation, we present two new methods for feature extraction of handwriting texture.

These two methods are based on signal processing techniques : the first is based on Power Spectrum (PS) ; whereas the second is based on Laws' Filtering (LF).

Their effectiveness compared to multiple channels (Gabor) filters and the gray-level co-occurrence matrix (GLCM) is shown.

The Gabor and the GLCM are well known methods proved to yield high performance in writer identification in Latin.

In our experimentations, texture features are extracted for wide range of frequency and orientations.

This is mainly due to the nature of Arabic handwritten which constitutes more spreaders compared to Latin.

The most discriminate features are selected using a proposed model for feature selection based on hybrid Support Vectors Machine (SVM) / and Genetic Algorithm (GA) techniques.

Three classification methods are used for classification, namely; Linear Discriminate Classifier (LDC), Support Vectors Machine (SVM), and the K nearest-neighbors (K-NN) classifier.

Experiments are made using Arabic handwritings from 20 different people and very promising results of 90 % identification rate is achieved.
