N2 - Self-Organising Maps (SOMs) have been successfully applied to
content-based image retrieval (CBIR). In this study, we investigate the
potential of PicSOM, an image database browsing system, applied to remote
sensing images. Databases of small images were artificially created, either
from a single satellite image for object detection, or two satellite images
when considering change detection. By visually querying those databases, it
was possible to detect targets like houses, roads or man-made structures, as
well as changes between two QuickBird images. Results open a full range of
applications, from structure detection to change detection, to be embedded in
a same operative system. The framework may be particularly suitable for
long-term monitoring of strategic sites.
