• Multilinear sparse decomposition for best spectral bands selection 

      Bouchech, Hamdi Jamel; Foufou, Sebti; Abidi, Mongi ( Springer Verlag , 2014 , Conference Paper)
      Optimal spectral bands selection is a primordial step in multispectral images based systems for face recognition. In this context, we select the best spectral bands using a multilinear sparse decomposition based approach. ...
    • Multiple Relay Selection and Beamforming in Dual-Hop Amplify-and-Forward Relay Networks 

      Gouissem, Ala; Samara, Lutfi; Hamila, Ridha; Al-Dhahir, Naofal; Foufou, Sebti ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)
      In this paper, the problems of multiple relay selection and beamforming optimization are considered for a dual-hop amplify-and-forward relaying network under individual and total power constraints. The selection is performed ...
    • Multispectral image denoising using optimized vector NLM filter 

      Said, Ahmed Ben; Foufou, Sebti ( Springer Verlag , 2016 , Conference Paper)
      In this paper, we present a Stein's Unbiased Risk Estimator (SURE) approach for Non-Local Mean filter to denoise multispectral images. We extend this filter to the vector case in order to take advantage from the additional ...
    • Multispectral image denoising with optimized vector non-local mean filter 

      Ben Said, Ahmed; Hadjidj, Rachid; Melkemi, Kamal Eddine; Foufou, Sebti ( Elsevier Inc. , 2016 , Article)
      Nowadays, many applications rely on images of high quality to ensure good performance in conducting their tasks. However, noise goes against this objective as it is an unavoidable issue in most applications. Therefore, it ...
    • PTNet: A parameterizable data center network 

      Baccour, Emna; Foufou, Sebti; Hamila, Ridha ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      This paper presents PTNet, a new data center topology that is specifically designed to offer a high and parameterized scalability with just one layer architecture. Furthermore, despite its high scalability, PTNet grants a ...
    • Re-parameterization reduces irreducible geometric constraint systems 

      Barki, Hichem; Fang, Lincong; Michelucci, Dominique; Foufou, Sebti ( Elsevier Ltd , 2016 , Article)
      You recklessly told your boss that solving a non-linear system of size n (n unknowns and n equations) requires a time proportional to n, as you were not very attentive during algorithmic complexity lectures. So now, you ...
    • Total Variation for Image Denoising Based on a Novel Smart Edge Detector: An Application to Medical Images 

      Ben Said, Ahmed; Hadjidj , Rachid; Foufou, Sebti ( Springer New York LLC , 2019 , Article)
      In medical imaging applications, diagnosis relies essentially on good quality images. Edges play a crucial role in identifying features useful to reach accurate conclusions. However, noise can compromise this task as it ...
    • VacoNet: Variable and connected architecture for data center networks 

      Chkirbene, Zina; Foufou, Sebti; Hamila, Ridha ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      Todays data centers may contain tens of thousands of computers with progressively more specialized and expensive equipments. Thus, the research community has proposed various interconnect topologies e.g FatTree, Dcell and ...
