8. The method of claim 7 , wherein said conditional probability means comprises computing said frame importance value as one of a Gaussian, Poisson, Rayleigh and Bernoulli distribution.
8. The method of claim 7 , wherein said conditional probability means comprises computing said frame importance value as one of a Gaussian, Poisson, Rayleigh and Bernoulli distribution. 9. The method of claim 8 , further comprising computing the Gaussian distribution according to the equation: P ⁡ ( s | θ ) = θ 2 2 ⁢ π ⁢ ⅇ - ( 1 / 2 ) ⁢ θ 2 ⁡ ( x - θ 1 ) where: θ is any of the features; θ 1 is the average of the feature value; and θ 2 is the expected deviation.
