      An embedded saliency map estimator scheme: Application to video encoding 

      Tsapatsoulis, Nicolas; Rapantzikos, K.; Pattichis, Constantinos S. (2007)
      In this paper we propose a novel saliency-based computational model for visual attention. This model processes both top-down (goal directed) and bottom-up information. Processing in the top-down channel creates the so ...
