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 abiertoWe 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 ... -
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 abiertoWe 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) ... -
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 abiertoThis 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 ... -
Field-Programmable Wiring Systems
Murray, Victor; Pattichis, Marios; Llamocca, Daniel (Institute of Electrical and Electronics Engineers, 2015-07)Acceso abiertoField-programmable wiring systems refer to methods and hardware that can maintain the interconnection of components of different types. Generally, field-programmable wiring systems support the use of multidomain fabrics ... -
Hardware implementation of a FPGA-based universal link for LVDS communications
Sanchez, Luis; Patiño, Giancarlo; Murray, Victor; Lyke, James (Institute of Electrical and Electronics Engineers, 2015-02-27)Acceso abiertoWe present the first hardware implementation for a FPGA-based universal link for the transmission of different low-voltage differential signaling (LVDS) connections through a single LVDS connection between different devices. ... -
Real-time diabetic retinopathy patient screening using multiscale AM-FM methods
Murray, Victor; Agurto, Carla; Barriga, Simon (Institute of Electrical and Electronics Engineers, 2012-10)Acceso abierton this paper we present a robust and improved system for diabetic retinopathy (DR) screening. The goal of the system is to automatically screen out digital fundus photographs of diabetic patients who do not present signs ... -
Research laboratories and training undergraduate students from the freshman level to produce international conference-level publications
Murray, Victor; Matsuno, Cecilia (Institute of Electrical and Electronics Engineers, 2014-12)Acceso abiertoWe present the first results of the teaching methodology applied at the Universidad de Ingeniería y Tecnología (UTEC), Lima, Peru, to involve undergraduate engineering students in advanced research projects starting at ... -
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 abiertoWe 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. ...
