Michael Gienger, Mark Toussaint, Christian Goerick , "Task maps in humanoid robot manipulation", IEEE International Conference on Intelligent Robot and Systems, 2008.
AbstractThis paper presents an integrative approach to solve the coupled problem of reaching and grasping an object in a cluttered environment with a humanoid robot. While finding an optimal grasp is often treated independently from reaching to the object, in most situations it depends on how the robot can reach a pregrasp pose while avoiding obstacles. We tackle this problem by introducing the concept of task maps which represent the manifold of feasibl...

Stefan Menzel and Bernhard Sendhoff , "Representing the Change - Free Form Deformation for Evolutionary Design Optimisation", Evolutionary Computation in Practice, Springer, pp. 63–86, 2008.
AbstractThe representation of a design influences the success of any kind of optimization significantly. The perfect trade-off between the number of parameters which define the search space and the achievable design flexibility is very crucial since it influences the convergence speed of the chosen optimization algorithm as well as the possibility to find the design which provides the best performance. Classical methods mostly define the design directly,...

Sven Rebhan, Florian Röhrbein, Julian Eggert, Edgar Körner , "Attention Modulation Using Short- and Long-Term Knowledge", ICVS 2008, issue 5008, pp. 151–160, 2008.
AbstractA fast and reliable visual search is crucial for representing visual scenes. The modulation of bottom-up attention plays an important role here. The knowledge about target features is often used to bias the bottom-up pathway. In this paper we propose a system which does not only make use of knowledge about the target features, but also uses already acquired knowledge about objects in the current scene to speed up the visual search. Main ingredien...

Ingo Fründ, Jeanette Schadow, Niko Busch, Nicole Naue, Ursula Körner, Christoph Herrmann , "Anticipation of natural stimuli modulates EEG dynamics: physiology and simulation", Cognitive Neurodynamics, vol. 2, no. 2, pp. 89-100, 2008.
AbstractIn everyday life we often encounter situations in which we can expect a visual stimulus before we actually see it. Here, we study the impact of such stimulus anticipation on the actual response to a visual stimulus. Participants were to indicate the sex of deer and cattle on photographs of the respective animals. On some trials, participants were cued on the species of the upcoming animal whereas on other trials this was not the case. Time freque...

Nils Einecke, Sven Rebhan, Julian Eggert , "Depth from Perspective Transformations", 5th HRI Global Workshop, 2008.
AbstractAll binocular depth estimation algorithms need to apply some kind of matching process for correspondence search. Unfortunately, this search process is difficult because of ambiguities. One possibility to reduce ambiguities is to use 3-D models of the scene geometry. In this paper we interpret the scene as a composition of basic parameterizable surfaces. We present a general way of deriving formulas for perspectively mapping such surfaces from one...

AbstractDuring CAD development and any kind of design optimisation over years a huge amount of geometries accumulate in a design department. To organize and structure these designs with respect to reusability, a hierarchical set of components on different scalings is extracted by the designers. This hierarchy allows to compose designs from several parts and to adapt the composition to the current task. Nevertheless, this hierarchy is imposed by humans an...

AbstractApplying numerical optimisation methods in the field of aerodynamic design optimisation normally leads to a huge amount of heterogeneous design data. While most often only the most promising results are investigated and used to drive further optimisations, general methods for investigating the entire design dataset are rare. We propose methods that allow the extraction of comprehensible knowledge from aerodynamic design data represented by discre...
