CBMI 2013 — Deadline extended to March 11, 2013

The 11th International Content Based Multimedia Indexing Workshop is to bring together the various communities involved in all aspects of content-based multimedia indexing, retrieval, browsing and presentation. Following the ten successful previous events of CBMI (Toulouse 1999, Brescia 2001, Rennes 2003, Riga 2005, Bordeaux 2007, London 2008, Chania 2009, Grenoble 2010, Madrid 2011, and Annecy 2012), the University of Pannonia, Hungary organizes the 11th Context Based Multimedia Indexing Workshop on June 17-19 2013 in the historical town of Veszprém, Hungary, near the spectacular Lake Balaton. The workshop will host invited keynote talks and regular, special and demo sessions with contributed research papers.

New Book: Visual Information Retrieval using Java and LIRE

Finally! Our book on LIRE is published! It was an incredibly long way to get there, but it was worth it! We are also very happy with our publisher, especially as the ebook PDF version starts as low as 20$! So it’s definitely more affordable than comparable books! The book gives an introduction to the fields of information retrieval and visual information retrieval and points out selected methods as well as their use and implementation within LIRE. It’s intended to be a fully fledged course for those that want either to employ LIRE in their projects or those who want to build upon and extend LIRE. Find the book here.

Abstract. Visual information retrieval (VIR) is an active and vibrant research area, which attempts at providing means for organizing, indexing, annotating, and retrieving visual information (images and videos) from large, unstructured repositories.

The goal of VIR is to retrieve matches ranked by their relevance to a given query, which is often expressed as an example image and/or a series of keywords. During its early years (1995-2000), the research efforts were dominated by content-based approaches contributed primarily by the image and video processing community. During the past decade, it was widely recognized that the challenges imposed by the lack of coincidence between an image’s visual contents and its semantic interpretation, also known as semantic gap, required a clever use of textual metadata (in addition to information extracted from the image’s pixel contents) to make image and video retrieval solutions efficient and effective. The need to bridge (or at least narrow) the semantic gap has been one of the driving forces behind current VIR research. Additionally, other related research problems and market opportunities have started to emerge, offering a broad range of exciting problems for computer scientists and engineers to work on.

In this introductory book, we focus on a subset of VIR problems where the media consists of images, and the indexing and retrieval methods are based on the pixel contents of those images — an approach known as content-based image retrieval (CBIR). We present an implementation-oriented overview of CBIR concepts, techniques, algorithms, and figures of merit. Most chapters are supported by examples written in Java, using Lucene (an open-source Java-based indexing and search implementation) and LIRE (Lucene Image REtrieval), an open-source Java-based library for CBIR.
