which is very similar to the general MSER (Equation ). It differs only by the factor of 1 Var [n 0 ,N ] (A(x)) . This will decrease sensitivity to bias compared to MSER, because an initial transient will increase Var [n 0 ,N ] (A(x)), but this effect is expected to be small when autocorrelation is thoroughly accounted for (by considering all important terms in the autocorrelation function), as in Chodera's work. ) by adding all autocovariance terms (Equation )
