As part of our collaboration with the Institute of Bioscience. We have been asked to create a small program that is able to track and register the amount of boats passing through part of Sejerøbugten. There is a radar placed on Nekselø which generates pictures like this every 3 minutes.

As you might notice there is a lot of noise in the image so a basic mask is created to subtract the ground. To help identify moving objects a trail is added between signals (If you look at the center of the radar and to the left, you should see a red dot, with a blue “tail” – this is a boat). By filtering out the noise and masking the image correctly, in this case using OpenCV – we can track overlaps of these “tails” and in that way show the path that the boat traveled.
