Eugene Borovikov

Dr. Eugene Borovikov is an Image Processing/Computer Vision scientist. He joined NIH/NLM/CEB team as a contractor in April 2011 and is actively contributing to the R&D efforts of the Lost Person Finder (LPF) project by researching and developing face detection and matching capabilities in unconstrained images. During 2003-2010 he was an active member of the R&D team at CACI-Lanham primarily involved in multilingual OCR/ICR and NLP efforts in the document recognition/understanding area, authoring numerous papers and book chapters on Arabic OCR and handwriting recognition. In 2006, Dr. Borovikov directed an R&D team at ADF Solutions, advancing technology for content based image and video retrieval, collaborating with academic labs such as LAMP at UMCP. During 1997-2003, Eugene Borovikov worked as a Research Assistant at UMCP's Computer Vision Lab, performing research in the area of non-rigid shape recognition in applications to 3D human body shape estimation.

Eugene Borovikov received his Ph.D. degree from University of Maryland, College Park in 2003, with the dissertation titled "High-performance visual computing in multi-perspective environments", advised by professors Larry Davis and Alan Sussman. Eugene Borovikov received the degree of Master of Arts in Applied Mathematics from University of Maryland, College Park in 1998 with the thesis titled "Human Head Pose Estimation by Facial Features Location", advised by professors Larry Davis and David Harwood.

Szilard Vajda
Dr. Vajda, joined Lister Hill National Center for Biomedical Communications, an intramural R&D division of the National Library of Medicine (NLM), at the National Institutes of Health (NIH) in April 2012 as research fellow, and concentrates his research on pattern recognition, machine learning with special application to document analysis, handwriting recognition, face detection/recognition and related topics such as classification, supervised/unsupervised/semi-supervised learning, clustering methods, automatic feature learning strategies and human-computer interaction.
