Start-up Polar Rose plans early next year to launch technology designed to more efficiently search for photos on the Web.
The Swedish company essentially takes a two-dimensional photograph and extrapolates it into a 3D model. A computer then takes the 3D model and searches for photo matches on the Internet and in public photo sites like Flickr.
The 3D model, although virtual, allows a computer to filter out differences related to the lighting, the camera angle, and the angle of the subject's face in two or more photos. Such differences can otherwise throw off search results. By filtering out differences, the search results are more accurate, according to Jan Eric Solem, founder and CTO. Even if one photograph is a direct head shot, Polar Rose's search engine can turn up three-quarter and profile shots.
