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
