Pairwise Semantic Stereo Challenge

Pairwise Semantic Stereo Challenge is one of the challenges of the 2019 IEEE GRSS Data Fusion Contest, organized by the Image Analysis and Data Fusion Technical Committee. The contest aims to promote research in semantic 3D reconstruction and stereo using machine intelligence and deep learning applied to satellite images.

The objective is to predict both 3D geometric models and segmentation maps of semantic classes for urban scenes from pairs of epipolar rectified satellite images.

The problem is to predict semantic labels and stereo disparities. Each input is a pair of epipolar rectified satellite images. You are intended to submit 2D semantic segmentation and stereo disparities in TIFF with the same height and width as the input image.

The contest will consist of two phases:

  • Phase 1: Development phase. We provide you with training data (which includes ground truth) and validationn data (without ground truth). You can submit prediction results for the validation set to Codalab to get feedback on the performance. The performance of your LAST submission will be displayed on the leaderboard.
  • Phase 2: Final phase. The test data set (without the corresponding ground truth) will be released on March 7, 2019. You can submit your predictions of semantic labels and stereo disparities from March 7 to March 22, 2019. In parallel, you need to submit a short paper of 2 pages describing the used approach by March 26, 2019. Please send a paper to iadf_chairs@grss-ieee.org using the IGARSS paper template. After evaluation of the results, we will announce two winners on March 29, 2019.

Performance is assessed using the pixel-wise mean Intersection over Union (mIoU) combined with the percentage of erroneous pixels with a threshold of 3 pixels for disparity values. We call this metric mIoU-3. The evaluation code is available at https://github.com/pubgeo/dfc2019.

The winners will have approximately one month (submission deadlline: April 26, 2019) to write their manuscript that will be included in the IGARSS 2019 proceedings. Manuscripts are 4-page IEEE-style formatted. Each manuscript describes the addressed problem, the proposed method, and the experimental results.
