Patent ID: 7403642

Claim:
A method, comprising: selecting digital images; assigning a name to the digital images; and propagating the name from the digital images to a face of an individual represented in each of the digital images; wherein the propagating includes applying a similarity measure: to define an objective function as a sum of similarities between multiple features of each pair of faces of the individual in different selected images, and to maximize the objective function in order to associate the name with the face in each image; and wherein applying the similarity measure includes integrating the multiple features into a Bayesian framework according to: S ⁡ ( F 1 , F 2 ) = ∏ j = 1 N f ⁢ ⁢ p ⁡ ( Δ ⁢ ⁢ f i | Ω I ) ⁢ p ⁡ ( Ω I ) ∏ i = 1 N f ⁢ ⁢ p ⁡ ( Δ ⁢ ⁢ f i | Ω I ) ⁢ p ⁡ ( Ω I ) + ∏ j = 1 N f ⁢ ⁢ p ⁡ ( Δ ⁢ ⁢ f i | Ω E ) ⁢ p ⁡ ( Ω E ) where p(Ω I ) and p(Ω E ) are a priors, Δf i =(f i1 −f i2 ), and p(Δf i |Ω I ) and p(Δf i |Ω E ) are the likelihoods of a given difference Δf i between the features.
