Figure 7From: Markov random field modeling for mapping geofluid distributions from seismic velocity structuresEstimated behavior of the hyperparameters during the method of steepest descent, at the depth of 40 km. (a) Variance of continuity of porosity σ ϕ 2 and aspect ratio σ α 2 ; (b) variance of the observational noise in VP σ P 2 and VS σ S 2 .Back to article page
