Julia Vogel

Dr. sc. techn.

In February 2005, I joined the Max-Planck Institute for Biological Cybernetics in Tubingen, Germany to work with Adrian Schwaninger and Christian Wallraven on some projects concerning the psychophysics of human scene perception.

 

From August 2005, I'll start a position as post-doctoral research fellow at the Laboratory for Computational Intelligence of the University of British Columbia, Vancouver, Canada. I'll work with Kevin Murphy on statistical methods for scene understanding.

Short Bio

In November 2004, Julia Vogel completed her PhD on Semantic Scene Modeling and Retrieval under the supervision of Bernt Schiele (now Darmstadt Technical University, Germany). Her PhD project was situated in the context of content-based image retrieval (CBIR). Especially, she investigated methods for semantically describing photographic images or scenes through the use of local semantic concepts. The developed methods were verified and extended based on psychophysical experiments. Earlier work of Julia include the performance prediction and optimization of a CBIR system.

 

Before starting her PhD, Julia obtained a M.Sc. (Dipl.Ing.) in Electrical Engineering from the University of Karlsruhe, Germany in 2000 and a M.Sc. in Electrical and Computer Engineering from Oregon State University, Corvallis, OR in 1998. Julia's master's thesis at the University of Karlsruhe was conducted in the field of digital signal processing and spectral estimation of speech signals. The thesis titled Echo Compensation with Frequency-Selective Step-Size Control proposes a frequency-based solution to the problem of echo compensation in a non-stationary environment (e.g. hands-free communications). Julia's research at Oregon State University investigated the effects of circuit level distortions on system level performance. In her master's thesis A New Correction Algorithm for Gain and Phase Imbalances in a Homodyne Receiver an algorithm is proposed that corrects for certain circuit level distortions in low power receivers.
