A FCM and SURF based algorithm for segmentation of multispectral face images
( IEEE , 2013 , Conference Paper)In this paper, we propose a novel clustering algorithm based on Fuzzy C-Means (FCM) and Speeded-Up Robust Feature (SURF) for multispectral image segmentation. In the experiments, color images and multispectral images from ... -
An energy-efficient distributed clustering algorithm for heterogeneous WSNs
( Springer International Publishing , 2015 , Article)Wireless sensor networks (WSNs) were envisaged to become the fabric of our environment and society. However, they are yet unable to surmount many operational challenges such as limited network lifetime, which strangle their ... -
Cluster validity index based on Jeffrey divergence
( Springer London , 2017 , Article)Cluster validity indexes are very important tools designed for two purposes: comparing the performance of clustering algorithms and determining the number of clusters that best fits the data. These indexes are in general ... -
A Differentially Private Big Data Nonparametric Bayesian Clustering Algorithm in Smart Grid
( IEEE Computer Society , 2020 , Article)Smart systems, including smart grid (SG) and Internet of Things (IoT), have been playing a critical role in addressing contemporary issues. Taking full advantage of the big data generated by the smart grid can enhance the ... -
Exploring use of unsupervised clustering to associate signaling profiles of GPCR ligands to clinical response.
( Springer Nature , 2019 , Article)Signaling diversity of G protein-coupled (GPCR) ligands provides novel opportunities to develop more effective, better-tolerated therapeutics. Taking advantage of these opportunities requires identifying which effectors ... -
Gravitational weighted fuzzy c-means with application on multispectral image segmentation
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper presents a novel clustering approach based on the classic Fuzzy c-means algorithm. The approach is inspired from the concept of interaction between objects in physics. Each data point is regarded as a particle. ... -
An Investigation into the Lifestyle, Health Habits and Risk Factors of Young Adults
( MDPI AG , 2015 , Article)This project examined the lifestyle, health habits and risk factors of young adults at Qatar University. It explored the clustering and differences in dietary habits, body mass index (BMI) and physical activity (PA) amongst ... -
Multi-criteria classification, sorting, and clustering: a bibliometric review and research agenda
( Springer Nature Switzerland AG. , 2022 , Article)Multi-criteria decision analysis (MCDA) has been increasingly adopted to solve decision-making problems involving multiple options and multiple criteria. These methods have been proven to improve the analytic rigor, ... -
