Overview
The growing capacity of computers, the abundance of digital cameras and the
increased connectivity of the world all point to large digital multimedia
archives. They include images and videos from the World Wide Web, museum
objects, flowers, trademarks, and views from everyday life. The faster they
grow, the more prominently needed is the efficient access to the content of
the images and videos.
In this short course, we will give a survey of the most recent developments on
image and video search engines. First, the important step of feature
extraction will be discussed in detail such as color, shape and texture
information, particularly paying attention to discriminatory power and
invariance. Then, we focus on the concepts of indexing and genre
classification as intermediate step to sort the data. We pay attention to
(interactive) ways to perform browsing and retrieval by means of information
visualization and relevance feedback. Methods are being discussed to localize
the retrieved objects in images.
Outline
The following important aspects will be covered:
·
Feature extraction and learning
·
Object recognition and image classification
·
Visual tracking
·
(Active) learning in image and video retrieval
·
Affective video retrieval
·
Video retrieval benchmarking
·
Applications in image and video retrieval
Biographies
Theo Gevers is an Associate Professor of Computer Science at the University of Amsterdam, The Netherlands and an ICREA
Research Professor at the Computer Vision Center (UAB), Barcelona, Spain. At the University of Amsterdam he is a teaching director of the MSc of Artificial Intelligence. His main research
interests are in the fundamentals of content-based image retrieval, colour image processing and computer vision specifically
in the theoretical foundation of geometric and photometric invariants. He is
co-chair of the Internet Imaging Conference (SPIE 2005, 2006), co-organizer
of the First International Workshop on Image Databases and Multi Media Search
(1996), the International Conference on Visual Information Systems (1999,
2005) and the Conference on Multimedia & Expo (ICME, 2005). He is guest
editor of the special issue on content-based image retrieval for the
International Journal of Computer Vision (IJCV 2004) and the special issue on
Colour for Image Indexing and Retrieval for the
journal of Computer Vision and Image Understanding (CVIU 2004). He has
published over 100 papers on colour image
processing, image retrieval and computer vision. He is program committee
member of a various number of conferences, and an invited speaker at major
conferences. Further, he is a lecturer of post-doctoral courses given at
various major conferences (CVPR, ICPR, SPIE, CGIV).
He is member of the IEEE.
Nicu Sebe
is an Assistant Professor in the Faculty of Science, University of Amsterdam, The Netherlands, where he is
doing research in the areas of multimedia information retrieval and
human-computer interaction in computer vision applications. He is the author
of the following books: Robust Computer Vision -Theory and Applications (Kluwer, April 2003) and Machine Learning in Computer
Vision (Springer, May 2005). He was a guest editor of a CVIU special issue on
video retrieval and summarization (December 2003) and was the co-chair of ACM
Multimedia Information Retrieval Workshops, MIR' 03 & MIR' 04 (in
conjunction with ACM Multimedia conferences). He also was the co-chair of the
first Human Computer Interaction Workshop, HCI' 04 (in conjunction with ECCV
2004) and of the IEEE Workshop on Human computer Interaction Workshop (in
conjunction with ICCV 2005). He is the guest editor of three special issues
on multimedia information retrieval and human computer interaction in ACM
Transactions on Multimedia Computing, Communication, and Applications, ACM
Multimedia Systems, and Image and Vision Computing. He was the technical
program chair for the International Conference on Image and Video Retrieval,
CIVR 2003. He was a visiting researcher in the Beckman Institute, University of Illinois at Urbana-Champaign (2002) and was a
research fellow of the British Telecomm in Ipswich, UK (2003). He has published more
than 60 technical papers in the areas of computer vision, content-based
retrieval, pattern recognition, and human-computer interaction and has served
on the program committee of several conferences in these areas. He is a
member of the IEEE and the ACM.
Arnold W.M. Smeulders is Professor of
Computer Science in Multi Media Information Analysis. He heads the
Intelligent Sensory Information Systems ISIS-group at the University of Amsterdam. His current research interest is
in computer vision from first principles, texture and material perception,
image retrieval and learning object segmentation and visual concepts rather
than modelling it and the language - pictorial
barrier. He has published some 200 papers and an equal amount of conference
contributions. Last year he has edited special issues on content-based image
retrieval for IJCV and CVIU. This year he is program chair of the CIVR
conference on Image and Video Retrieval. He is a fellow of the IAPR and an
associated editor of IJCV.
