How Sensitive Is the Human Visual System to the Local Statistics of Natural Images?

Figure 12

Experiment 4 results.

Discriminability estimates with 95% binomial confidence intervals are shown by model in order of increasing likelihood where data are pooled over subjects and patch sizes (, , , and ). Seven subjects participated, and each performed 36 test trials per model per patch size per condition, so each data point is based on trials. Unfilled bars are for the grayscale high contrast stimuli, and filled bars the binary version. Within the range of the error bars, the estimates for the grayscale stimuli followed the same ordering as in Experiment 1, yet the data for the binary stimuli show no ordering.
