A, First row: Three frames from a natural movie used in the experiment, taken one second apart. Second through sixth rows: frames from the five clips with the highest posterior probability. The maximum a posteriori (MAP) reconstruction is shown in row two. Seventh row: The averaged high posterior (AHP) reconstruction. The MAP provides good reconstruction of the second and third frames, while AHP provide more robust reconstructions across frames. B and C, Additional examples of reconstructions, format same as in panel A. D, Reconstruction accuracy (correlation in motion-energy; see Supplemental Information) for all three subjects. Error bars indicate ± 1 s.e.m. across one-second clips. Both the MAP and AHP reconstructions are significant, though the AHP reconstructions are significantly better than the MAP reconstructions. Dashed lines show chance performance (P=0.01). See also Figure S2.
