Abstract : Change detection is perhaps the most important task in the process of photo-interpretation, and an ideal one to demonstrate the effectiveness of the site modeling exploitation (SME) approach that has been adopted for the RADIUS program. Change detection is a tedious task as it requires careful comparison of images (and their models) taken at different times under possibly varying conditions. The task of change detection consists of comparing a new image of a site (or a collection of images), to the information contained in the folder for that site. The information in the site folder may consist of one or more previous images and results of previous analyses on these images. We believe that even partial automation of this task will greatly increase an analyst's productivity and possibly enhance the reliability of the results. (MM)
