Web-based 3D virtual environments suffer from the classic problem of users getting ’lost-in-cyberspace’. Apart from getting lost, it is hard for an average user to discover all that a specific...
Exact matching in image databases (2008)
Peter Bosch, Alex Van Ballegooij, Martin Kersten
We believe there is a niche for exact sub-image searching in image databases. When only a sub-image is searched for, traditional image searching approaches fail because the sub-image features usually...

A Probabilistic Multimedia Retrieval Model and Its Evaluation (2003)
Thijs Westerveld, Alex Van Ballegooij, Franciska De Jong, Djoerd Hiemstra
We present a probabilistic model for the retrieval of multimodal documents. The model is based on Bayesian decision theory and combines models for text-based search with models for visual search. The...
