  • 3d semantic representation of actions from effcient stereo-image-sequence segmentation on GPUs 

    Alexey, Abramov; Aksoy, Eren Erdal; Dörr, Johannes; Wörgötter, Florentin; Pauwels, Karl; Dellen, Babette (2010)
    Conference report
    Open Access
    A novel real-time framework for model-free stereo-video segmentation and stereo-segment tracking is presented, combining real-time optical flow and stereo with image segmentation running separately on two GPUs. The ...
  • Categorizing object-actions relations from semantic scene graphs 

    Aksoy, Eren Erdal; Abramov, Alexey; Wörgötter, Florentin; Dellen, Babette (2010)
    Conference report

    In this work we introduce a novel approach for detecting spatiotemporal object-action relations, leading to both, action recognition and object categorization. Semantic scene graphs are extracted from image sequences and ...
  • Execution of a dual-object (pushing) action with semantic event chains 

    Aksoy, Eren Erdal; Dellen, Babette; Tamosiunaite, Minija; Wörgötter, Florentin (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
    Conference report
    Open Access
    Execution of a manipulation after learning from demonstration many times requires intricate planning and control systems or some form of manual guidance for a robot. Here we present a framework for manipulation execution ...
  • Learning the semantics of object-action relations by observation 

    Aksoy, Eren Erdal; Abramov, Alexey; Dörr, Johannes; Ning, Kejun; Dellen, Babette; Wörgötter, Florentin (2011-10-28)
    Article
    Open Access
    Recognizing manipulations performed by a human and the transfer and execution of this by a robot is a difficult problem. We address this in the current study by introducing a novel representation of the relations between ...
  • Segment tracking via a spatiotemporal linking process including feedback stabilization in an n-D lattice model 

    Dellen, Babette; Aksoy, Eren Erdal; Wörgötter, Florentin (2009)
    Article
    Open Access
    Model-free tracking is important for solving tasks such as moving-object tracking and action recognition in cases where no prior object knowledge is available. For this purpose, we extend the concept of spatially synchronous ...
