Sven Rebhan, Florian Röhrbein, Julian Eggert, Edgar Körner , "Attention Modulation Using Short- and Long-Term Knowledge", LNCS 2008, 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...

Irene Ayllón Clemente , "Investigation and Implementation of a level-set based tracking system, incorporating contour prediction by means of different, collaborating prediction algorithms", TU Darmstadt, 2008.
AbstractObject tracking is a challenging task in many computer vision applications such as automated surveillance systems, driver assistance and humanoid robots. A crucial step in object tracking is object segmentation, which is in charge of the detection of the object to track. Level set methods are a powerful approach for image segmentation. These methods are based on the iterative deformation of a surface, the level set function, which provides the co...

Tobias Rodemann, Gökhan Ince, Frank Joublin, Christian Goerick , "Using Binaural and Spectral Cues for Azimuth and Elevation Localization", IEEE-RSJ International Conference on Intelligent Robot and Systems (IROS 2008), 2008.
AbstractIt is a common assumption that with just two microphones only the azimuth angle of a sound source can be estimated and that a third, orthogonal microphone (or set of microphones) is necessary to estimate the elevation of the source. Recently, using specially designed ears and analyzing spectral cues several researchers managed to estimate sound source elevation with a binaural system. In this work, we show that with two bionic ears both azimuth a...

AbstractThe design of a system that bootstraps an open-ended development is one of the most intriguing questions in Developmental Robotics. Inspired by evolution we propose an incremental design. We start with a reactive layer that provides task-unspecific interaction with the environment. We extend this initial layer by a layer of multi-modal expectation generation. The two layers are coupled by means of an active resolution of expectation mismatches. S...

Jan Biel , "Core Knowledge for a Humanoid Robot Based on Findings in Human Infant Research", TU Clausthal, 2008.
AbstractConverging evidence from the field of cognitive science promotes the assumption that certain core abilities might be available to the human infant from birth. One of these is the ability to discriminate between inanimate objects and agents. Furthermore, studies with infants show that the ability to infer the goal of an agent is available to the human child within its first year of life. These findings provide an interesting interface with the fie...

Philipp Schwesig , "Development of a Realtime System for Gender Adaptive Formant Extraction", University of Applied Sciences Frankfurt, 2008.
AbstractThe purpose of this diploma thesis is the extension of the existing formant extraction system to the parameter of the gender. The formants describing the resonance frequencies of the vocal tract are slightly different for male and female speakers. This was the essential point leading to the attempt of improving the robustness of the existing formant extraction system by the gender information. Previous to this diploma thesis it has been shown tha...

AbstractFor the interaction of a mobile robot with a dynamic environment, the estimation of object motion is desired while the robot is walking and/or turning its head. In this paper, we describe a system which manages this task by combining depth from a stereo camera and computation of the camera movement from robot kinematics in order to stabilize the camera images. Moving objects are detected by applying optical flow to the stabilized images followed ...
