Automatic detection of regions in spinach canopies responding to soil moisture deficit using combined visible and thermal imagery
(
Public Library of Science
, 2014 , Article)
Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of ...
Novel geometric features for off-line writer identification
(
Springer Verlag
, 2014 , Article)
Writer identification is an important field in forensic document examination. Typically, a writer identification system consists of two main steps: feature extraction and matching and the performance depends significantly ...
Coalitional double auction for spatial spectrum allocation in cognitive radio networks
(
IEEE
, 2014 , Article)
Recently, many dynamic spectrum allocation schemes based on economics are proposed to improve spectrum utilization in cognitive radio networks (CRNs). However, existing mechanisms do not take into account the economic ...

In recent years, amateur UAVs have become more and more popular. This is due to the decreasing cost and growing range of applications such as weather monitoring, cargo transport and recreational purposes. However, ...
Cross Layer NOMA Interference Mitigation for Femtocell Users in 5G Environment
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, we propose a joint channel allocation and power control algorithm by using cognitive radio non-orthogonal multiple access (CR-NOMA) for femtocell users (FUs). The aim is to maximize the sum rate of the FUs ...
A kernelized sparsity-based approach for best spectral bands selection for face recognition
(
Springer Verlag
, 2015 , Article)
We study face recognition in unconstrained illumination conditions. A twofold contribution is proposed: First, the robustness of four state-of-the-art algorithms, namely Multi-block Local Binary Pattern (MBLBP), Histogram ...
