The effect of fixational eye movements on model performance.

(A) Horizontal and vertical and 2D displacements in units of cones of the retinal image over time. Colors indicate eye movement paths of 5 example trials. A 1D slice of a single cycle of the Gabor stimulus is shown as the background (red box). (B) Computational observer performance with eye movements and stimulus phase shifts (red dashed), phase shifts only (red solid), eye movements only (black dashed) and neither (black solid). Accuracy is averaged across 5 simulated experiments which each have 400 trials per stimulus contrast. Error bars represent standard error of the mean across the 5 simulated experiments for each stimulus contrast.
