So, how soon before Google and the other main search engines begin to use recognition technologies as primary means in their ranking algorithms for video search?
It appears that the first step has been taken by Google in that they are now leading the charge to be able to determine the subject and content of a image without relying on metadata and alt tags in their ranking algorithms for image search.
Two scientists from Google presented a research paper at the WWW conference in China last week, titled "Page Rank for Product Image Search." The research presented what is called, VisualRank, a new algorithm that uses image recognition technology to identify, rank, and weight images automatically based on the resulting analysis of the image content. The algorithm can also identify similar images which may lead to duplicate content filtering for image search.
