There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened. (Douglas Adams)

Content Based Image Retrieval with LIRe

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.

Short CV

www.itec.uni-klu.ac.at_mlux_images_mlux-head.jpgAss. Prof. Dipl.-Ing. Dr. Mathias Lux is Associate Professor at the Institute for Information Technology (ITEC) at Klagenfurt University. He is working on user intentions in multimedia retrieval and production and emergent semantics in social multimedia computing. In his scientific career he has (co-) authored more than 80 scientific publications, has served in multiple program committees and as reviewer of international conferences, journals and magazines, and has organized multiple scientific events. Mathias Lux is also well known for the development of the award winning and popular open source tools Caliph & Emir and LIRe (http://www.semanticmetadata.net) for multimedia information retrieval.

Dr. Mathias Lux received his M.S. in Mathematics 2004, his Ph.D. in Telematics 2006 from Graz University of Technology, both with distinction, and his Habilitation (venia docendi) from Klagenfurt University in 2013. 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.

  • CrowdMM 2014 @ ACM MM Call for Papers (2014/04/11 18:22)
    The power of crowds – leveraging a large number of human contributors and the capabilities of human computation – has enormous potential to address key challenges in the area of multimedia research. Crowdsourcing offers a time- and resource-efficient method for collecting large volumes of input for system design and evaluation, making it possible to optimize […]
  • CfP: 11th International Workshop on Text-based Information Retrieval (2014/02/18 15:47)
    Intelligent algorithms for data mining and information retrieval are the key technology to cope with the information need challenges in our media-centered society. Methods for text-based information retrieval receive special attention, which results from the important role of written text, from the high availability of the World Wide Web, and from the enormous impact of […]
  • ACM MMSys 2014 Dataset Track – Approaching Submission Deadline (2013/11/05 17:05)
    As an integral part of the ACM MMSys conference since 2011, the Dataset Track provides an opportunity for researchers and practitioners to make their work available (and citable) to the multimedia community. MMSys encourages and recognizes dataset sharing, and seeks contributions in all areas of multimedia (not limited to MM systems). Authors publishing datasets will benefit […]
  • ACM Multimedia Presentation & LIRE Solr (2013/10/24 22:58)
    Today I gave a talk on LIRE at the ACM Multimedia conference in the open source software competition, currently taking place in Barcelona. It gave me the opportunity to present a local installation of the LIRE Solr plugin and the possibilities thereof. Find the slides of the talk at slideshare: LIRE presentation at the ACM Multimedia […]
  • New LIRE web demo based on Apache Solr (2013/08/13 14:46)
    The new LIRE web demo is based on Apache Solr and features and index of the MIRFLICKR data set. The new architecture allows for extremely fast retrieval. Moreover, there’s a new walk through video with some short peeks behind the screen. The source of the plugin will be released in the near future.
