Indexing flower patent images using domain knowledge
Mousumi Das, Raghaven Manmatha, Edward M. Riseman · IEEE Intelligent Systems and their Applications · 1999
The article explains how to query a database of flower patent images using both an example flower image and color names. This database consists of images that have been digitized from photographs submitted as a part of applications for flower patents to the US Patents and Trademark Office. This database must be queried by both example images and color name, so that both those checking new patent applications and those buying patents for cultivation can use it.
