Recognition of off-line handwritten Arabic words using neural network
( IEEE , 2006 , Conference Paper)Neural network (NN) have been used with some success in recognizing printed Arabic words. In this paper, a complete scheme for unconstrained Arabic handwritten word recognition based on a Neural network is proposed and ... -
Writer identification of arabic handwriting documents using grapheme features
( IEEE , 2008 , Conference Paper)[No abstract available] -
Round-Robin sequential forward selection algorithm for prostate cancer classification and diagnosis using multispectral imagery
( Springer , 2011 , Article)This paper proposes an automatic classification system for the use in prostate cancer diagnosis. The system aims to detect and classify prostatic tissue textures captured from microscopic samples taken from needle biopsies. ... -
A new web-based project and employee time tracking system for project management
( EMCIS , 2010 , Conference Paper)Project and Time Tracking System (PTTS) is a web application that provides an automated and centralized method of tracking and monitoring work time for active projects by enabling supervisors to track employees work time, ... -
Writer identification using edge-based directional probability distribution features for Arabic words
( IEEE , 2008 , Conference Paper)A system for writer identification based on Arabic handwritten words was built. First a database of words was gathered and used as a test base. Then, features vectors were extracted from writers' word images. Prior to ... -
The ICDAR2011 Arabic writer identification contest
( IEEE , 2011 , Conference Paper)Arabic writer identification is a very active research field. However, no standard benchmark is available for researchers in this field. The aim of this competition is to gather researchers and compare recent advances in ... -
Forensic handwritten document management system
( IEEE , 2008 , Conference Paper)[No abstract available] -
An online signature verification system for forgery and disguise detection
( Springer , 2012 , Conference Paper)Online signatures are acquired using a digital tablet which provides all the trajectory of the signature as well as the variation in pressure with respect to time. Therefore, online signature verification achieves higher ... -
Text-dependent writer identification for arabic handwriting
( Hindawi Publishing Corporation , 2012 , Article)This paper proposes a system for text-dependent writer identification based on Arabic handwriting. First, a database of words was assembled and used as a test base. Next, features vectors were extracted from writers' word ... -
A new chaos-based image-encryption and compression algorithm
( Hindawi Publishing Corporation , 2012 , Article)We propose a new and efficient method to develop secure image-encryption techniques. The new algorithm combines two techniques: encryption and compression. In this technique, a wavelet transform was used to decompose the ... -
A set of geometrical features for writer identification
( Springer , 2012 , Conference Paper)Writer identification is an important field in the forensic document examination. We propose in this paper a set of geometrical features that makes it possible to characterize writers. They include directions, curvatures ... -
An improved palmprint recognition system using iris features
( Springer , 2013 , Article)This paper presents a bimodal biometric recognition system based on the extracted features of the human palmprint and iris using a new graph-based approach termed Fisher locality preserving projections (FLPP). This new ... -
Systolic architecture for hardware implementation of two-dimensional non-separable filter-bank
( IEEE , 2013 , Conference Paper)In this paper, we present an efficient poly-phase decomposition scheme for implementation of 2-D non-separable filter bank. Poly-phase decomposition scheme offers multiplexing of filter bank computations or/and reduce the ... -
Automatic handedness detection from off-line handwriting
( IEEE , 2013 , Conference Paper)In forensics, the handedness detection or the classification of writers into left or right-handed helps investigators focusing more on a certain category of suspects. However, only a few studies have been carried out in ... -
Enhancing face recognition using Directional Filter Banks
( Elsevier Inc. , 2013 , Article)Face recognition is an increasingly important problem in biometric applications; consequently many recognition algorithms have been proposed during the last three decades. It is accepted that the use of a pre-processing ... -
A multi-modal face and signature biometric authentication system using a max-of-scores based fusion
( Springer , 2012 , Conference Paper)Face and signature based multimodal biometric systems are often required in various areas, such as banking biometric systems and secured mobile phone operating systems, among others. Our system combines these two biometric ... -
The evolution of scholarly digital library needs in an international environment: Social reference management systems and Qatar
( Springer Verlag , 2013 , Conference Paper)Qatar has become an active research producer of data, publications, and other scholarly works. We studied the evolving scholarly activities and needs of researchers in this relatively new research environment, and compared ... -
QUWI: An Arabic and English handwriting dataset for offline writer identification
( IEEE , 2012 , Conference Paper)This paper presents a new offline dataset called the Qatar University Writer Identification dataset (QUWI). This dataset contains both Arabic and English handwritings and can be used to evaluate the performance of offline ... -
