Evaluation

The problem is to predict a semantic label for each 3D point. Each input is a lidar point cloud dataset in ASCII. You are intended to submit semantic labels in ASCII with the same number of rows as the input ASCII file.

The contest will consist of two phases:

• Phase 1: Development phase. We provide you with labeled training data and unlabeled validationn data. 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 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). 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.
