Center node: "egosampling wide view hyperlapse from single and multiple egocentric videos"
  Abstract: The possibility of sharing one's point of view makes use of wearable cameras compelling. These videos are often long, boring and coupled with extreme shake as the camera is worn on a moving person. Fast forwarding (i.e. frame sampling) is a natural choice for faster video browsing. However, this accentuates the shake caused by natural head motion in an egocentric video, making the fast forwarded video useless. We propose EgoSampling, an adaptive frame sampling that gives more stable, fast forwarded, hyperlapse videos. Adaptive frame sampling is formulated as energy minimization, whose optimal solution can be found in polynomial time. We further turn the camera shake from a drawback into a feature, enabling the increase of the field-of-view. This is obtained when each output frame is mosaiced from several input frames. Stitching multiple frames also enables the generation of a single hyperlapse video from multiple egocentric videos, allowing even faster video consumption.

Connected through hyperedge HE-1 (induced by source paper "towards semantic fast forward and stabilized egocentric videos"):

    - "a fast and accurate unconstrained face detector"
    - "fast forward video based on semantic extraction"
    - "compact cnn for indexing egocentric videos"
