Yup! That's exactly why there has been so much work on this from the likes of Google. Video and images represent a "dark media" in terms of indexing and search.

Yup! That's exactly why there has been so much work on this from the likes of Google. Video and images represent a "dark media" in terms of indexing and search. It is very difficult without robust tagging (which is time intensive or relies on the articles and descriptions that surround the images) to search through images. This technology would make it much easier perform robust querying of this data.
