Figure 3From: Markov random field modeling for mapping geofluid distributions from seismic velocity structuresEstimated behavior of the hyperparameters during the method of steepest descent. (a) Variances of continuity of porosity (ϕ) and aspect ratio (α), and (b) variances of noise in the observational data, VP and VS. The empty circles indicate the true values of the variances.Back to article page
