Efficient and effective techniques for managing and browsing large image databases are increasingly sought after. This chapter presents a simple yet efficient and effective approach to navigating image datasets. Based on the concept of a globe as visualisation and navigation medium, thumbnails are projected onto the surface of a sphere based on their colour. Navigation is performed by rotating and tilting the globe as well as zooming into an area of interest. Experiments based on a medium size image database demonstrate the usefulness of the presented approach.
Chapter Preview

Several approaches which provide a more intuitive interface for image database navigation, compared to the traditional linear display of thumbnails, have been recently introduced in the literature. Rubner et al. were among the first (Rubner, Guibas, & Tomasi, 1997) and suggested the application of multidimensional scaling (MDS) (Kruskal & Wish, 1978) to calculate the locations of images and displaying them in a global 2-dimensional view on a single screen. Using this method, all images in a database are (initially) shown simultaneously; their locations are dependent on their visual similarity (based on features such as colour, texture or shape descriptors) compared to all other images features in the database. If two images are very similar in content they will also be located close to each other on the screen and vice versa. The user can browse the database easily from a top-down hierarchical point of view in an intuitive way.
