Multimedia Analytics: Exploration of Large Multimedia Collections.

Multimedia collections, in particular images and videos, are a new and promising source of insight and knowledge in various disciplines. Exploring the content of the collections can only be done when the data is properly analyzed and categorized. When done manually this is a tedious and time-consuming task. Progress in automatic indexing of visual material brings us to a point where tools can help to reduce the effort. As the indexing of visual material is difficult and ambiguous, the quality of the indexing, however, has a limit. As a consequence, much of the categorization is still fully manual. We develop methods which bring the interacting user and the data together through automatic indexing, machine learning, and advanced visualization methods. In this presentation we show the underlying principles of these techniques and how they aid the user in the exploration and categorization processes.
