ICPR2012 Tutorials PM-05
Visualisation and browsing of large image repositories

Gerald Schaefer
Loughborough University, U.K.



Image database visualisation and browsing systems provide a visual overview of image collections together with means of interactively browsing through the image dataset. As such they have been shown to provide a useful alternative to query based image retrieval systems.
In this tutorial we will discuss image database visualisation based on image features and timestamp information, will look at the principal methods of visualising image databases, in particular approaches based on dimensionality reduction, clustering and graph structures, and will cover the various browsing operations that can be offered in such systems.

 We will further look at immersive image browsing (i.e. image browsing using VR hardware), at mobile image browsing (using smartphones and other portable devices), and discuss the issue of evaluation which so far has received relatively little attention.
