    • On quantized compressed sensing with saturated measurements via convex optimization 

      Elleuch, Ines; Abdelkefi, Fatma; Siala, Mohamed; Hamila, Ridha; Al-Dhahir, Naofal ( European Signal Processing Conference, EUSIPCO , 2016 , Conference Paper)
      In this paper, we address the problem of sparse signal recovery, from multi-bit scalar quantized compressed sensing measurements, where the saturation issue is taken into account. We propose a convex optimization approach, ...

    • Quasi-sparsest solutions for quantized compressed sensing by graduated-non-convexity based reweighted ?1minimization 

      Elleuch, Ines; Abdelkefi, Fatma; Siala, Mohamed; Hamila, Ridha; Al-Dhahir, Naofal ( European Signal Processing Conference, EUSIPCO , 2016 , Conference Paper)
      In this paper, we address the problem of sparse signal recovery from scalar quantized compressed sensing measurements, via optimization. To compensate for compression losses due to dimensionality reduction and quantization, ...

    • Self-organizing binary encoding for approximate nearest neighbor search 

      Ozan, Ezgi Can; Kiranyaz, Serkan; Gabbouj, Moncef; Hu, Xiaohua ( European Signal Processing Conference, EUSIPCO , 2016 , Conference Paper)
      Approximate Nearest Neighbor (ANN) search for indexing and retrieval has become very popular with the recent growth of the databases in both size and dimension. In this paper, we propose a novel method for fast approximate ...
