For block-matching methods, information from neighboringmatching blocks has been utilized to regularize the estimated dis-placements. We apply a recursive bayesian regularization algo-rithm developed by Haytonet al.[Artif. Intell., vol. 114, pp. 125 156, 1999] to phase-sensitive ultrasound RF signals to improvedisplacement estimation. The parameter of regularization is re-formulated, and its meaning examined in the context of strainimaging.
