Tracking – Visual Computing Lab https://viscomp.alexandra.dk Computer Graphics, Computer Vision and High Performance Computing Tue, 20 Sep 2016 11:56:23 +0000 en-GB hourly 1 https://wordpress.org/?v=5.8.2 Boat-tracking at “Sejerøbugten” https://viscomp.alexandra.dk/?p=3822 https://viscomp.alexandra.dk/?p=3822#respond Fri, 13 Feb 2015 12:55:20 +0000 http://viscomp.alexandra.dk/?p=3822 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.

Kinect 2 for windows developer kit https://viscomp.alexandra.dk/?p=2066 https://viscomp.alexandra.dk/?p=2066#respond Tue, 04 Feb 2014 11:51:13 +0000 http://viscomp.alexandra.dk/?p=2066 Its been a while since we received a developer preview of Kinect 2 for windows, but we forgot to let you all know about it.

It came in a decorated box.

Well protected.

All shiny and street with it’s stickers 🙂

It’s good looking and definitely will be much easier to integrate in an installation than its predecessor. It’s a regular box with two cameras one hidden and one visible, so the front needs to be unobstructed for the device to work. Underneath the unit the microphone array is placed which makes it much cleaner looking. There is no motorized foot on the device which is compensated with a greater field of view.

Our initial tests with the device look very promising and we will write a future post about our findings. If you have an application that you would like to prototype or test on the device do not hesitate to contact us.
