Wireless body area sensor networks signal processing and communication framework: Survey on sensing, communication technologies, delivery and feedback
(
Science Publication
, 2012 , Article)
Problem statement: The Wireless Body Area Sensor Networks (WBASNs) is a wireless network used for communication among sensor nodes operating on or inside the human body in order to monitor vital body parameters and movements. ...
Delay minimization through joint routing and resource allocation in cognitive radio-based mesh networks
(
IEEE
, 2012 , Conference Paper)
We consider wireless mesh networks in which the nodes are utilizing cognitive radios and try to opportunistically gain access to spectrum resources. In such networks, the timely delivery of the traffic is a challenging ...
QUMESH: Wireless mesh network deployment and configuration in harsh environment
(
IEEE
, 2012 , Conference Paper)
The link delivery probability in a wireless mesh network is most accurately determined only by experiment, as it depends on many factors, including environment characteristics, transmission power, distance between transmitter ...
ICFHR2012 competition on writer identification - Challenge 2: Arabic scripts
(
IEEE
, 2012 , 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 ...
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 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 ...
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 ...
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 ...
