in Association with the 2012 ECCV Workshop on Unsolved Problems in Optical Flow and Stereo EstimationVideo cameras provide information on a scene with low cost in acquisition, space and energy, and at the same time high spatio-temporal resolution. To extract depth and motion information from a video computer vision algorithms make strong assumption on a scene. The algorithms are thus easily distracted by phenomenons that violate these assumptions, such as reflecting or transparent surfaces, lens flares, and changing illuminations.
We recorded multiple real world scenes that contain instances of challenging phenomenons such as they occur in every-day traffic scenarios. To be applicable in industry, image based depth and motion estimation needs to deal robustly and reliably with these scenes.
We pose the estimation of depth and motion on our recorded sequences as a challenge to the scientific community. Can you develop an stereo or optical flow algorithm that can deal with with these sequences?
For the evaluation of participating algorithms we bring together a jury of renowned experts on the application of stereo and motion estimation. In the absence of ground-truth information, the jury will thoroughly inspect and evaluate the submitted correspondences and their applicability in industry. A prize for the best-performing algorithm is awarded by Bosch.
The WinnerThe winner of the challenge where Simon Hermann and Reinhard Klette with a SGM variant.
Please find details in our ECCV Workshop Winner Announcement!
The TaskEstimate robust and reliable depth or motion fields on our challenging real world videos!
Download image sequences
The sequences contain many examples for regularly occurring situations causing problems with most methods known today. We are looking for algorithms that can produce reliable depth or motion estimates for all images, including the indicated keyframes. Participation is open to all ideas that improve the state-of-the-art in automatic motion and depth estimation on the given input videos!
This could involve (but is not limited to):
- Previously unknown methods of correspondence estimation
- Correspondence estimation making use of confidence measures
- Correspondence estimation with a detection of unreliable input images or unreliable image regions
ParticipationAll authors of algorithms that estimate stereo correspondences or motion correspondences or stereo and motion correspondences from the input images and are accepted for publishing in any journal or conference proceedings can participate.
Due to heavy server load we extended the deadline to September 24, 2012.
You can find detailed submission instructions here. (deadline ended!)
The evaluation of this challenge is part of the "2012 ECCV Workshop on Unsolved Problems in Optical Flow and Stereo Estimation" taking place October 12th, 2012 in Florence, Italy.
For each submission at least one team-member should assist in a discussion during the workshop.
Note that participation in the challenge is independent of the publication of any articles within the workshop. However we encourage the participants to also publish or revise their ideas and methods within this framework.
If you have any questions concerning your participation please contact us under hcibenchmark -at- hci.iwr.uni-heidelberg.de
EvaluationThe input images for the challenge are real world videos recorded in an uncontrolled environment. The actual depths and object motions visible in the scenes are unknown. For the evaluation we rely on the capability of human observers to judge whether a correspondence is roughly correct. Although that does not allow for a quantitative evaluation, we believe the sequences to be so challenging that qualitative evaluation is sufficient.
The human jury that evaluates the motion and stereo results consists of eight experts in the usage of image correspondences in various applications. Each jury member is going to look at the provided visualizations and may additionally use his or her own tools to evaluate the submitted material. We documented some of the expectations on motions fields and also the tools that will be used to visualize correspondence fields. Depending on the decision of the jury among the sufficiently stable and reliable correspondence algorithms the most applicable algorithm is awarded a prize of 3000€ that is kindly provided by Bosch.
