Visual comparisons between the prior and posterior predictors based on images from the USC-SIPI database. Numerical data express the PSNRs. (a) Ground truth/aeroplane. (b) Ground truth/Lena. (c) Ground truth/mandrill. (d) Ground truth/peppers. (e) Prior/32.9055 dB. (f) Prior/34.5666 dB. (g) Prior/28.5752 dB. (h) Prior/35.3336 dB. (i) Posterior/36.3609 dB. (j) Posterior/37.6200 dB. (k) Posterior/29.3495 dB. (l) Posterior/39.9355 dB.
