Ingo Fründ, Niko Busch, Ursula Körner, Jeanette Schadow, Christoph Herrmann, "EEG oscillations in the gamma and alpha range respond differently to spatial frequency", Vision Research, vol. 47, no. 15, pp. 2086-2098, 2007.
AbstractPhysical properties of visual stimuli affect electrophysiological markers of perception. One important stimulus property is spatial frequency (SF). Therefore, we studied the influence of SF on human alpha (8-13Hz) and gamma (>30Hz) electroencephalographic (EEG) responses in a choice reaction task. Since real world images contain multiple SFs, an SF mixture was also examined. Event related potentials were modulated by SF around 80 and 300ms. Evoke...

Julian Eggert, Volker Willert, Jens Schmüdderich, "Biological Motion Estimation with Spatiotemporal Integration", HRI Global Workshop, 2007.
AbstractWe present a framework and study a model for biologically inspired motion estimation. It comprises several “areas” (corresponding roughly to V1-MT) which locally analyze motion input at different levels of granularity, coupled to functionally distinct areas which concentrate on the extraction of more global motion patterns (corresponding e.g. to MST). The areas are coupled reciprocally with each other, with “higher” areas providing prior ...

Stephan Hasler, Heiko Wersing, Edgar Körner, "A Comparison of Features in Parts-based Object Recognition Hierarchies", Artificial Neural Networks – ICANN 2007, pp. 210–219, 2007.
AbstractParts-based recognition has been suggested for generalizing from few training views in categorization scenarios. In this paper we present the results of a comparative investigation of different feature types with regard to their suitability for category discrimination. So patches of gray-scale images were compared with SIFT descriptors and patches from the high-level output of a feedforward hierarchy related to the ventral visual pathway. We disc...

Christian Goerick and Edgar Körner, "Elements of Cognitive Robotics", it - Information Technology, vol. 49, no. 4, pp. 213-217, 2007.
AbstractIn this paper we present our research aiming at creating a cognitive humanoid. We describe our understanding of the core elements of a processing architecture for such kind of an artifact. After these conceptual considerations we present our research results in the areas of task and body oriented motion control as well as visually and behaviorally oriented learning....

Ingo Fründ, Jeanette Schadow, Niko Busch, Ursula Körner, Christoph Herrmann, "Evoked gamma oscillations in human scalp EEG are test-retest reliable", Clinical Neurophysiology, vol. 118, no. 1, pp. 221–227, 2007.
AbstractOBJECTIVE: Evoked, phase-locked gamma oscillations of the electroencephalogram (EEG) have been demonstrated to be modulated by both bottom-up as well as top-down factors. However, to date the test-retest reliability of these oscillations has not been studied systematically. METHODS: We recorded EEG activity of 12 healthy volunteers in response to stimuli of different sizes. Each participant took part in two sessions separated by two weeks in time...

Hisashi Sugiura, Michael Gienger, Herbert Janßen, Christian Goerick, "Real-Time Collision Avoidance with Whole Body Motion Control for Humanoid Robots", IEEE-RSJ International Conference on Intelligent Robots and Systems (IROS 2007), 2007.
AbstractWe propose a self collision avoidance system that superposes trajectories in order not only to protect the robot's hardware but also to enable continuous motions. The system runs in real-time so that the robot can work in an uncertain environment. It is based on virtual forces between close segments of the robot. The avoidance movements are blended with a whole body motion control in order to change the priority between target reaching and collis...

Rüdiger Kupper, Marc-Oliver Gewaltig, Andreas Knoblauch, Ursula Körner, Edgar Körner, "From neurons to cortex: a multi-level approach to understanding the brain", Neurocomputing Research Trends, Nova Science Publishers, Inc., 2007.
AbstractAt the Honda Research Institute, we aim to understand the operating principles of the brain. We think that the cortex is composed of elementary building blocks, the columns, that apply one generic algorithm to varying sensory data. The brain is thus not a collection of highly specialized neural circuits, providing tailored solutions to individual problems, but it uses the same set of powerful processing strategies over and over again. Based on ne...
