    • A novel real-time edge-preserving smoothing filter 

      Reich, Simon; Abramov, Alexey; Papon, Jeremie; Worgotter, Florentin; Dellen, Babette (2013)
      Conference report
      Open Access
      The segmentation of textured and noisy areas in images is a very challenging task due to the large variety of objects and materials in natural environments, which cannot be solved by a single similarity measure. In this ...
    • Categorizing object-actions relations from semantic scene graphs 

      Aksoy, Eren Erdal; Abramov, Alexey; Wörgötter, Florentin; Dellen, Babette (2010)
      Conference report
      Restricted access - publisher's policy
      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 ...
    • Depth-supported real-time video segmentation with the Kinect 

      Abramov, Alexey; Pauwels, Karl; Papon, Jeremie; Wörgötter, Florentin; Dellen, Babette (2011)
      Conference report
      Restricted access - publisher's policy
      We present a real-time technique for the spatiotemporal segmentation of color/depth movies. Images are segmented using a parallel Metropolis algorithm implemented on a GPU utilizing both color and depth information, acquired ...
    • 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 ...
    • Modeling leaf growth of rosette plants using infrared stereo image sequences 

      Eren Erdal, Aksoy; Abramov, Alexey; Worgotter, Florentin; Scharr, Hanno; Fischbach, Andreas; Dellen, Babette (2015)
      Article
      Open Access
      In this paper, we present a novel multi-level procedure for finding and tracking leaves of a rosette plant, in our case up to 3 weeks old tobacco plants, during early growth from infrared-image sequences. This allows ...
    • Real-time segmentation of stereo videos on a portable system with a mobile GPU 

      Abramov, Alexey; Pauwels, Karl; Papon, Jeremie; Wörgötter, Florentin; Dellen, Babette (2012)
      Article
      Open Access
      In mobile robotic applications, visual information needs to be processed fast despite resource limitations of the mobile system. Here a novel real-time framework for model- free spatio-temporal segmentation of stereo ...
    • Thermoresponsive shape-memory hydrogel actuators made by phototriggered click chemistry 

      Maiti, Binoy; Abramov, Alexey; Enshaei, Hamidreza; Díaz Díaz, David; Alemán Llansó, Carlos (2020-04-24)
      Article
      Open Access
      This article describes the design and synthesis of a new series of hydrogel membranes composed of trialkyne derivatives of glycerol ethoxylate and bisphenol A diazide (BA-diazide) or diazide-terminated PEG600 monomer via ...
