Application of Data Mining Tools for Recognition of Tifinagh Characters

Author 1: M. OUJAOURA Author 2: R. EL AYACHI Author 3: O. BENCHAREF Author 4: Y. CHIHAB Author 5: B. JARMOUNI

The majority of Tifinagh OCR presented in the literature does not exceed the scope of simulation software such as Matlab. In this work, the objective is to compare the classification data mining tool for Tifinagh character recognition. This comparison is performed in a working environment using an Oracle database and… Read full abstract & cite →

Annotation and research of pedagogical documents in a platform of e-learning based on Semantic Web

Author 1: S. BOUKIL Author 2: C. DAOUI Author 3: B. BOUIKHALENE Author 4: M.FAKIR

E-learning is considered as one of the areas in which the Semantic Web can make a real improvement whatsoever in finding information, or reusing of educational resources or even personalized learning paths. This paper aimsto develop an educational ontology that will be used to annotate learning materials and pedagogical documents. Read full abstract & cite →

Hierarchical Algorithm for Hidden Markov Model

Author 1: SANAA CHAFIK Author 2: DAOUI CHERKI

The Forward algorithm is an inference algorithm for hidden Markov models, which often leads to a very large hidden state space. The objective of this work is to reduce the task of solving the Forward algorithm, by offering faster improved algorithm which is based on divide and conquer technique. Read full abstract & cite →

Review of Color Image Segmentation

Author 1: Abderrahmane ELBALAOUI Author 2: M.FAKIR Author 3: N.IDRISSI Author 4: A.MERBOUHA

This paper provides a review of methods advanced in the past few years for segmentation of color images. After a brief definition of the segmentation, we outline the various existing techniques, classified according to their approaches. We have identified five that are based approaches contours, those relying on notion of… Read full abstract & cite →

Invariant Descriptors and Classifiers Combination for Recognition of Isolated Printed Tifinagh Characters

Author 1: M. OUJAOURA Author 2: R. EL AYACHI Author 3: B. MINAOUI Author 4: M. FAKIR Author 5: B. BOUIKHALENE Author 6: O. BENCHAREF

In order to improve the recognition rate, this document proposes an automatic system to recognize isolated printed Tifinagh characters by using a fusion of 3 classifiers and a combination of some features extraction methods. The Legendre moments, Zernike moments and Hu moments are used as descriptors in the features extraction… Read full abstract & cite →

Handwritten Tifinagh Text Recognition Using Fuzzy K-NN and Bi-gram Language Model

Author 1: Said Gounane Author 2: Mohammad Fakir Author 3: Belaid Bouikhalen

In this paper we present a new approach in Tifinagh character recognition using a combination of, k-nearest neighbor algorithm and the bigram language model. After the preprocessing of the text image, and the word segmentation, for each image character, the k-NN algorithm proposes candidates weighted of their membership degree. Then… Read full abstract & cite →

Recognition of Amazigh characters using SURF & GIST descriptors

Author 1: H. Moudni Author 2: M. Er-rouidi Author 3: M. Oujaoura Author 4: O. Bencharef

In this article, we describe the recognition system of Amazigh handwritten letters. The SURF descriptor, specifically the SURF-36, and the GIST descriptor are used for extracting feature vectors of each letter from our database which consists of 25740 manuscripts isolated Amazigh characters. All the feature vectors of each letter form… Read full abstract & cite →

Printed Arabic Character Classification Using Cadre of Level Feature Extraction Technique

Author 1: S. Nouri Author 2: M.Fakir

Feature extraction techniques is important in character recognition, because they can enhance the efficacy of recognition in comparison to other approaches. This study aims to investigate the novel feature extraction technique called the Cadre of Level technique in order to represent printed characters and digits. This technique gives statistic and… Read full abstract & cite →
