Image segmentation nodes for ROS

Hello guys!

Check out this part of my (Bence Magyar) MSc thesis work where I created ROS nodes to mask regions in an image based on different attributes.

The nodes can be applied on each other’s output in a pipeline-style way.

They can help to speed up your Computer Vision algorithms by masking the not interesting (defined by you) regions of the images.


Happy segmenting!

Beaglebone and ROS + Webcam + remote ROS master (+OpenCV)

This tutorial assumes that you already have Ubuntu on your Beaglebone. If not, you can get it done this way: https://fleshandmachines.wordpress.com/2012/05/03/beaglebone-on-ubuntu-11-04/

Although Fuerte is out I don’t recommend it yet.
Connect to your BeagleBone using ssh.

A nice guide can be found to install ROS Electric here:



This is the post what we forgot to write :]. So who are we?
First I would like to introduce my friend Bence Magyar, he is a university student at ELTE (HU university), and he is learning computer science. And myself, I graduated as a programmer at the DE (HU university too).
We started to learn robotics, when we bought two NXTs. Our first project was a wall follower bot. Next summer he met an evil engineer and our project had been boosted. First we started to think in more electronics related things, second to make a good bot, we used a router. It is a cheap and easy way to make an wireless bot. Thats why we are posting things about OpenWRT and routers. OpenCV is more robotics related, and Bence is learning it now, I also want to learn image processing if I have time.
Our goal is to make robots, that will reach space and explore it. We have some robot projects ongoing, one is to make four rover and do some swarm technology.
Also we went to a robotic competition in our country, it’s called Hungarians On Mars ( or Magyarok a Marson in HU). The project files and documents can be found here.
We also have a robot working team, that’s called Buggers. You can see it’s the logo at the top.
Our goal with this blog to share our way of robotics, and help other people who stuck with the same problem.
