      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 ...

      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 ...

      Image analysis system for automated detection of breast cancer nuclei 

      Tsapatsoulis, Nicolas; Schnorrenberg, Frank; Pattichis, Constantinos S.; Kollias, Stefanos (IEEE Comp Soc, 1997)
      A study for breast cancer nuclei detection is presented in this paper. The proposed algorithm determines the centers of nuclei in biopsy images using block-based processing of the images followed by singular value decomposition ...

      Improved detection of breast cancer nuclei using modular neural networks 

      Schnorrenberg, F.; Tsapatsoulis, Nicolas; Pattichis, Constantinos S.; Schizas, Christos N.; Kollias, S.; Vassiliou, M.; Adamou, Adamos K.; Kyriacou, Kyriacos C. (2000)
      A modular neural network-based approach to detect and classify breast cancer nuclei stained for steroid receptors in hispathological sections is evaluated. The system named biopsy analysis support system (BASS) is designed ...

      Neural network assisted algorithm for automated detection of breast cancer nuclei 

      Tsapatsoulis, Nicolas; Schnorrenberg, Frank; Pattichis, Constantinos S.; Kollias, Stefanos; Schizas, Christos N. (IEEE, 1997)
      A neural network assisted algorithm used for the detection of nuclei in biopsy images is presented in this paper. This algorithm is combined in a logical AND form with an algorithm based on receptive fields to build the ...

      Palm geometry biometrics: A score-based fusion approach 

      Tsapatsoulis, Nicolas; Pattichis, Constantinos S. (2009)
      In this paper we present an identification and authentication system based on hand geometry. First, we examine the performance of three different methods that are based on hand silhouette and on binarized hand images and ...

      Region of interest video coding for low bit-rate transmission of carotid ultrasound videos over 3G wireless networks 

      Tsapatsoulis, Nicolas; Loizou, Christos P.; Pattichis, Constantinos S. (2007)
      Efficient medical video transmission over 3G wireless is of great importance for fast diagnosis and on site medical staff training purposes. In this paper we present a region of interest based ultrasound video compression ...
