Green Image
The Artisan system retrieves abstract trademark images by shape similarity. It analyzes each image to characterize key shape components, grouping image regions into families that potentially mirror human image perception, and then derives characteristic indexing features from these families and from the image as a whole. We have evaluated the retrieval effectiveness of our prototype system on more than 10,000 images from the UK Trade Marks Registry.
