Visual Cataloguing

Finding something by flipping through the pages of a catalogue - if the catalogue has THOUSANDS of pages - is practically impossible.  Because photobank and enterprise image storehouses are like catalogs with thousands of pages, more practical is using visual search.

Visual search allows you to say:    "Show me something like this ...", and your search key can be an image on your local computer or another image already in the collection.

 This is extremely powerful, whether you are an creative editor searching your enterprise's stock of production images, or a photo buyer searching a photobank.

This powerful capability is thanks to the special LTU visual content descriptor, the LTU Image DNA which describes and encodes the visual characteristics of an image.

LTU engine is able to display similar images by comparing the Image DNA of the query image with the Image DNA's of the photo collection.

• Queries may be weighted to emphasize color, or shape, or a balanced combination of the two.
• Images are displayed according to their closeness to the query image:  exact matching visual content first, then variations (such as images which may have been "cloned" from the query image) and then images which are different from the query, but which contain certain similarities.
