Values of contrast (C) and contrast-to-noise ratios (CNR) in dB between the inclusion and the background. All numbers are in dB. The Markov random field algorithm provides slightly better C than nearest neighbor interpolation and also provides higher CNR in the inclusion compared to linear interpolation. (MRF = Markov random field algorithm, NNB = nearest neighbor interpolation, LIN = linear interpolation).
