How Sensitive Is the Human Visual System to the Local Statistics of Natural Images?
Figure 7
Experiment 2 texture scrambles.
Here we show example textures for each model tested in Experiment 2: RND, ICA, L2, LP, IPS, GPS, and MEC16. Both A and B are scrambled versions of the corresponding model stimuli shown in Figure 4. On any single trial the observer viewed only one texture based on natural image samples and one texture based on samples from a single model. A. Global scrambles, where the pixels of each texture were scrambled as a final post-processing step. B. Sample scrambles, where the pixels of each image patch were scrambled individually to preserve variations in luminance histograms across samples.
