In this paper an application of the TS-SOM variant of the self-organising map algorithm on the problem of copyright theft
detection for bitmap images is shown. The algorithm facilitates the location of originals of copied, damaged or modified images
within a database of hundreds of thousands of stock images. The method is shown to outperform binary decision tree indexing
with invariant frame detection.
