      Biologically inspired region of interest selection for low bit-rate video coding 

      Tsapatsoulis, Nicolas; Pattichis, Constantinos S.; Rapantzikos, K. (2006)
      A variety of approaches have been proposed in the literature for Region-Of-Interest (ROI) estimation. In most of them the ROI definition is highly subjective, i.e., lacks scientific evidence in supporting the claim that ...
