Part A computer vision challenge

Teams can upload new submissions of their image prediction results at any moment during the week. The ground-truth images of each dataset will be shared one day after the release of the unseen images and will be available as “GroundTruth_SendX.json”.

On June 7th 2021 00:00 CET, the public board will be open.

On July 12th 2021 23:00 CET, the public board will be closed.

On July 13th teams will access the last dataset and submit their results from 12:00-12:10 CET. Results of all teams will be shared in the final event on July 14th, 2021.


The public score is calculated by the summation of the normalised mean squared error (NMSE) for each plant trait. This normalisation is needed to calculate a total error from all plant traits. In formula:

with m the number of plants traits {FreshweightShoot, DryweightShoot, Height, Diameter, LeafArea} and n the number of predictions.

Part B machine learning challenge

During the OnLine Challenge, teams will have two keys with which they can access the simulators. The keys can be found under the “My-Team” page.

Evaluation of the teams’ performances will be realized on the simulator available with the B-key “C**B-****-...”, every Monday from 12:00 CET until 13:00 CET.


The public score is calculated by the simulator ,which gives the net profit values:

Net Profit = Gains – Fixed costs – Variable costs
