Abstract
A technique is provided for generating scout or navigational images based upon a series of related images. The related images are analyzed to compute pixels of scout images, such as by determining a characteristic of aligned pixels of each of the related images. The scout or navigational images are then projections of the related images and individual rows or columns of the scout images correspond to individual images of the related set. One or more of the related images may then be accessed by review of the scout image or images. The scout images may be referred to in their own right for an overview of features of interest and may be modified by a user. The technique provides for efficient time management by allowing specific images to be identified in large image series, and facilitates intelligent use of bandwidth for accessing specific images in a viewer workstation.
