Current research interests
Main research interests are in Computer Vision and Machine Learning. A further interest is in biological vision, which is used as a source of inspiration for solving computer vision problems and for building enhanced vision systems that can compensate the strengths and weaknesses of both human and computer vision.
Brief biography
Prof. Barth leads the research on human and machine vision at the INB. He obtained his Ph.D in Electrical Engineering from the Technical University of Munich in 1994, was a Research Associate at the Department of Communications Engineering in Munich and a Visiting Fellow at the Department of Computer Science, Melbourne University, Australia, where he was supported by the Gottlieb-Daimler and Karl-Benz Foundation. He then was a researcher at the Department of Medical Psychology, University of Munich, and a Klaus-Piltz fellow at the Institute for Advanced Study in Berlin. In 1997/98 he was a member of the NASA Vision Science and Technology Group at NASA Ames, Moffet Field, California. In May 2000 he received a Schloessmann Award from the Max-Planck Gesellschaft. Since then, he initiated and conducted a number of basic and applied research projects, and started a few companies (e.g. ARTTS, GazeCom, PRC, gestigon).

Although motion is one of the strongest attentional cues in humans, it is still unknown how neglect patients visually explore their moving real-world environment.</p> <p>We therefore recorded eye movements at bedside in 19 patients with hemispatial neglect following acute right hemisphere stroke, 14 right-brain damaged patients without neglect and 21 healthy control subjects. Videos of naturalistic real-world scenes were presented first in a free viewing condition together with static images, and subsequently in a visual search condition. We analyzed number and amplitude of saccades, fixation durations and horizontal fixation distributions. Novel computational tools allowed us to assess the impact of different scene features (static and dynamic contrast, colour, brightness) on patients{\textquoteright} gaze.</p> <p>Independent of the different stimulus conditions, neglect patients showed decreased numbers of fixations in contralesional hemispace (ipsilesional fixation bias) and increased fixation durations in ipsilesional hemispace (disengagement deficit). However, in videos left-hemifield fixations of neglect patients landed on regions with particularly high dynamic contrast. Furthermore, dynamic scenes with few salient objects led to a significant reduction of the pathological ipsilesional fixation bias. In visual search, moving targets in the neglected hemifield were more frequently detected than stationary ones. The top-down influence (search instruction) could neither reduce the ipsilesional fixation bias nor the impact of bottom-up features.</p> <p>Our results provide evidence for a strong impact of dynamic bottom-up features on neglect patients{\textquoteright} scanning behaviour. They support the neglect model of an attentional priority map in the brain being imbalanced towards ipsilesional hemispace, which can be counterbalanced by strong contralateral motion cues. Taking into account the lack of top-down control in neglect patients, bottom-up stimulation with moving real-world stimuli may be a promising candidate for future neglect rehabilitation schemes.</p>}, url = {http://dx.doi.org/10.1016/j.neuropsychologia.2012.06.012}, url = {https://www.inb.uni-luebeck.de/fileadmin/files/publications/inb-publications/pdfs/MaDoSpGaHeBaHe12.pdf} } |
