Preparations before departure

Please prepare your laptops with all the necessary software installed and all the downloadable data downloaded. For this please follow the links below!

For the lab on Monday afternoon:
To prepare your laptop for the first day's lab session, please follow the steps described here.

For the lab on Tuesday afternoon:
Please download and install the following packages and softwares on your laptop:
  • The 2D-3D data package prepared by i3Mainz for the lab session should be readily downloaded on your device, from this link. (~3GB!) (You will need an archive software like WinRAR to extract the files). Zip archives are also available: code and datasets. The Matlab source code is also available in the package.
  • Matlab: We developed our algorithm using Matlab R2011b, but you can run the code on any newer version, and possibly some older releases as well.
  • Meshlab: for viewing, pre-processing, and segmenting 3D pointclouds. Download the latest version from here
  • Gimp: for 2D image segmentation. The latest version can be downloaded from here
  • A fast image viewer software of your choice, eg. IrfanView
For eventual data exchanges please bring a USB stick, and it is also recommended to have an external mouse.

During the Lab session on Tuesday please try to follow the steps descriped in this file.

Most conveniently by plane to Budapest Airport (BUD). Early booking of tickets is advisable.

From the Airport you may take the bus number 200E to Ferihegy railway station, and from there the direct IC train to Szeged. Trains depart from Ferihegy station from 6:13 to 21:13 every hour. For further information visit this website where you can buy an online ticket. You may also purchase a ticket at Ferihegy station at the ticket office or in a ticketing machine as well (priced at 3700 HUF one way). From the bus stop 200E you should take the pedestrian overpass, the tracks to Szeged are at the last exit. Find the ticket office under the stairs in a container.

Alternatively you may take an airport shuttle directly from the Airport to your hotel in Szeged starting at approx. 7000 HUF/person (1-2 hours waiting time may occur, see eg. Pegazus Transzfer)


The University is located in the city center where you can find numerous hotels (see map) for less than 60 EUR/night/person (breakfast included).
Some options within walking distance from the venue:

Kata Panzio
Mozart Hotel
Hotel Korona
Szent Janos Hotel
