On Thursday, the USPTO published Google's patent application for Automatically Mining Person Models of Celebrities for Visual Search Applications, in which the search giant describes how it used spectral analysis to construct a database of 'highly accurate biometric models' to allow it to recognize the faces of 30,000 celebrities wherever they might appear. Included in the patent drawings is Plot 104 of '141 images in Barack Obama's face model', which Google notes is much less 'polluted' than Plot 102 of '71 images in Britney Spears' face model.' Watch out, celebrity stalkers — there's a new kid in town!"
