The MDS-based visualization technique, described in the last chapter, makes it possible to display a large number of images in an intuitive way that allows the user to see at a glance the commonalities is the returned set of images and what part of the display is most relevant. In this chapter, we develop a navigation method based on this display. Once the user points to the region of interest on the display, the system zooms in and finds more images that are similar to the common features of the images in the region. By iterating this refinement process, the user can quickly home in to the relevant parts of the database. We show examples of navigation in a space of color images and in a space of police mugshots.
