    • An image watermarking algorithm via Zero Assigned Filter Banks 

      Yücel, Zeyep; Özgüler, A. Bülent (IEEE, 2005-12)
      In this paper a new method for digital image watermarking based on Zero Assigned Filter Banks and Embedded Zero Tree Wavelet (EZW) algorithm is presented. An image is partitioned into 128 × 128 subblocks and each block is ...
    • Watermarking based on discrete wavelet transform and q-deformed chaotic map 

      Behnia, Sohrab; Yahyavi, Mohammad; Habibpourbisafar, Reza (Elsevier Ltd, 2017)
      Hierarchy of one-dimensional ergodic chaotic maps with Tsallis type of q-deformation are studied. We find that in the chaotic region, these maps with q-deformation are ergodic as the Birkhoff ergodic theorem predicts. ...
