18:00 Wrap-up and closing remarks

For the workshop we had a dual-track submission program. One is the symmetry detection algorithm competition track and one is the applications of detected symmetry track.

Competition Track:

This competition is set-up as a three-stage process, though a participant can enter at any point.

    • Phase One: training image set and associated ground truth will be made available and image contributions are invited.
    • Phase Two: test image set is released;
    • Phase Three: symmetry detection submissions are invited, quantitatively evaluated, and decisions on winners will be made.
  • Top winners in each category will be invited to present their algorithm during the workshop as oral presentations. Selected top-ranked competitors will also be invited to present (either oral or poster).
  • The test images with annotations, evaluation standards, and winning algorithms will be made publicly available during and after the workshop.

Application Track:

In parallel, a CALL FOR PAPERS will be posted to invite the submission of original, scientific contributions on symmetry detection and its role in computer vision problems including, but not limited to:

    • Image/video editing
    • Saliency/attention
    • 3D reconstruction
    • Figure-ground (object) segmentation
    • Object recognition
    • Scene categorization
    • Urban scene parsing/reconstruction
  • At the same time as Phase Three of the Competition Track, we will accept submissions of papers on applications.
  • These papers will be reviewed by the organizing committee members and invited reviewers, and the top 3-5 will be selected as oral presentations
