Google is going into the business of selling virtual billboards.
Google says in the patent it could potentially update a movie theater's marquee in Street View with a current listing of shows, if the price is right.
Google's software first identifies interest points in the image (e.g. the edges or corners of an object) and then generates features around these interest points. Google can then augment this region of the image with a link or replace a part of the current Street View image with a new image.
But one potential problem is already lurking. Google's patent says the link could "be associated with an advertiser who placed the highest bid on the image." Does that mean a shop could have its own storefront plastered with a richer man's name?
