Macroglossa was a visual search engine based on the comparison of images,[1][2] coming from an Italian Group.

Included features are the categorization of the elements, the ability to search specific portions of the image or start a search from a video file,[4] but the main function is to simulate a digital eye on trying to find similarities of an unknown subject.

This technology allows users to pull results from collections of visual content[5] without using tags for search.

Macroglossa supports all popular image extensions such jpeg, png, bmp, gif and video formats such avi, mov, mp4, m4v, 3gp, wmv, mpeg.

Macroglossa enters beta stage in September 2011[6] and at the same time open to the public the opportunity to use the developed interfaces ( Api for web and mobile applications ) in order to expand the use of the engine in the B2B and B2C fields.
