Guest lecture at Passau University This semester I'm giving a guest lecture at Passau University on the development of computer games. It's an introductory course and it's based on the computer games course at Klagenfurt University last summer .

User intentions in multimedia is a novel and promising field as well as my main and most favourite research topic. Here are some interesting publications to read:

• C. Kofler, M. Lux (2009) Dynamic presentation adaptation based on user intent classification. ACM Multimedia 2009 ACM page
• M. Lux, C. Kofler, O. Marques (2010) A classification scheme for user intentions in image search. CHI 2010 ACM page
• M. Lux, M. Kogler, M. del Fabro (2010) Why did you take this photo: a study on user intentions in digital photo productions. SAPMIA 2010 ACM page
• M. Kogler, M. Lux, O. Marques (2011) Adaptive Visual Information Retrieval by changing visual vocabulary sizes in context of user intentions. MMWeb 2011 to be published by IEEE.
• C. Lagger, M. Lux, O. Marques (2011) Which video do you want to watch now? MMWeb 2011 to be published by IEEE.

LIRe (Lucene Image Retrieval) is an open source library for content based image retrieval. Besides providing multiple common and state of the art retrieval mechanisms it allows for easy use on multiple platforms. LIRe is actively used for research, teaching and commercial applications. Due to its modular nature it can be used on process level (e.g. index images and search) as well as on image feature level. Developers and researchers can easily extend and modify LIRe to adapt it to their needs.

Dr. Mathias Lux is currently assistant professor at the Institute for Information Technology at Klagenfurt University. He received his M.S. in Mathematics and his Ph.D. in Telematics from Graz University of Technology. He worked in industry on web-based applications, then as a junior researcher at a research center for knowledge-based applications. He was research and teaching assistant at the Knowledge Management Institute (KMI) of Graz University of Technology and in 2006 he started working in a post doc position at Klagenfurt University, at the Institute for Information Technology. In his scientific career he has (co-) authored more than 50 scientific publications and has served in multiple program committees of international conferences. He is also well known for managing the development of the award winning and popular open source tools Caliph & Emir and LIRe for multimedia information retrieval. He is currently working on user intentions in multimedia retrieval and production and emergent semantics in social multimedia computing.

• Links turning up in my feed :) (2012/01/11 17:35)

  Today and yesterday all in all 3 links from del.icio.us turned up in the news feed. Sorry for them, I haven’t published them. Unfortunately I have not logged in to my del.icio.us account for such a long time that my account has been deleted and re-enabled by another user. So it’s not a security breach, [...]
• LIRe presentation and poster at ACM MM 2011 (2011/11/29 23:18)

  Just finished my presentation at ACM MM’s open source competition in 2011. Many interested researchers and developers came by to discuss ideas and developments. I’m looking forward to turning many of those idea into code For those of you interested in the poster I uploaded it here. I also uploaded the presentation to slideshare.
• Searching with Lire in big datasets (2011/10/27 11:17)

  Having received several complaints about the slowness of Lire when searching in 100k+ documents I took my time to write a small how to to explain approaches for search in big (relatively) data sets. Lire has the ability to create indexes with lots of different features (descriptors, like RGB color histograms or CEDD). While this [...]
• Lire publication in the top 10 downloads of ACM SIGMM (2011/10/24 14:42)

  As to be found in this month’s SIGMM record, which is the electronic SIGMM newsletter, a publication about Lire is in the top 10 downloads of the ACM special interest group on multimedia for September 2011. I co-authored the paper with Savvas Chatzichristofis: Mathias Lux, Savvas A. Chatzichristofis. Lire: lucene image retrieval: an extensible java [...]
• Lire and Lire Demo v 0.9 released (2011/10/20 13:37)

  I just released Lire and Lire Demo in version 0.9 on sourceforge.net. Basically it’s the alpha version with additional speed and stability enhancements for bag of visual words (BoVW) indexing. While this has already been possible in earlier versions I re-furbished vocabulary creation (k-means clustering) and indexing to support up to 4 CPU cores. I [...]
