will truly be relevant in the case of video documents where these techniques should create new facets of video documents by breaking their rigid linear temporal structure. This will permit alternative navigation modes that we think should reveal interesting features of video documents.

Clearly, this will be done hand in hand with the development of Human-Computer Interaction (HCI) techniques to validate these advances. The goal is and remains that of having feed back between any development in Content-based Visual Data interpretation technique and relevant advances made in parallel fields. We do not wish to abandon the concept of fully automated visual content interpretation systems but rather to make them practical by including human interaction where (temporarily) needed.
