      We introduce a framework for synergistic arc-weight estimation and show its
      application to several interactive segmentation approaches using graphs. The method
      is a dynamic training process, where the user draws markers inside each object
      (including background), arc weights are estimated from image attributes and object
      information (pixels under the markers), and a visual feedback guides the next user's
      action. We demonstrate the advantages of the proposed framework with respect to
      methods that do not exploit object information for arc-weight estimation and methods
      that recompute weights during delineation, making the user to loose control over the
      segmentation process.
