Google purchased UK-based mobile visual search startup “Plink” for an undisclosed sum. Founded by PhD students Mark Cummins and James Philbin, Plink’s first product was PlinkArt, a visual recognition app for mobile that analyses pictures of well-known artworks and paintings and identifies them. Users can then share the photo with friends and also click through to buy a poster version.Plink says “othing is changing. PlinkArt will continue to be available for download and work as it currently does today. However, we won’t be updating the app and will instead focus our development efforts on Google Goggles, so you’ll see new functionality appearing there in the future.” The acquisition follows chief executive Eric Schmidt’s statement that Google is aiming to acquire at least one company each month – as well as recruit more staff – as it expands the company post-recession.
