    • A multiscale decomposition approach to detect abnormal vasculature in the optic disc 

      Agurto, Carla; Yub, Honggang; Murray, Victor; Pattichis, Marios; Nemeth, Sheila; Barriga, Simon; Soliz, Peter (Elsevier, 2015-07-01)
      Acceso abierto
      This paper presents a multiscale method to detect neovascularization in the optic disc (NVD) using fundus images. Our method is applied to a manually selected region of interest (ROI) containing the optic disc. All the ...

    • 2D Instantaneous Frequency-based Method for Motion Estimation using Total Variation 

      Murray, Victor; Rodriguez, Paul; Pattichis, Marios (Institute of Electrical and Electronics Engineers, 2014-12)
      Acceso abierto
      We present a first approach to a new method to compute the motion estimation in digital videos using the two-dimensional instantaneous frequency information computed using amplitude-modulation frequency-modulation (AM-FM) ...

    • Scalable Open-Source Architecture for Real-Time Monitoring of Adaptive Wiring Panels 

      Llamocca, Daniel; Murray, Victor; Jiang, Yuebing; Pattichi, Marios (American Institute of Aeronautics and Astronautics, 2014-06-06)
      Acceso abierto
      We recently introduced the first prototype of an Adaptive Wiring Panel (AWP) which implemented a reconfigurable switch fabric that allows dynamic routing of analog, digital, and power signals for space system applications. ...

    • 2D amplitude-modulation frequency-modulation - based method for motion estimation 

      Murray, Victor; Rodriguez, Paul; Noriega, Maria (Institute of Electrical and Electronics Engineers, 2015-02)
      Acceso abierto
      We present a new approach to compute the motion estimation in digital videos using 2D amplitude-modulation frequency-modulation (AM-FM) methods. The optical flow vectors are computed using an iteratively reweighted norm ...
