@ricardodeazambuja : Yes the observation is correct.
As described here:
The dataset contains 422 flights, 2056 total frames (5 frames per flight at different AGLs), Full semantic segmentation annotations of all frames and depth estimations. The dataset has been split into training and (public) test datasets. While the challenge will be scored using a private test dataset, we considered it useful to have this split to allow teams to share their results even after the challenge ends.
Of the total frames available, a subset if used for the (public) test set that you are currently being scored on. There will be an additional (private) test set that the final leaderboards will be based on. And submissions are currently limited to 5 submissions / day.
Best,
Mohanty
