Figure 3.

Impact of fixational eye movements. Top panels: Contrast sensitivity functions (CSFs) at the level of cone photopigment excitations, computed for a 3 mm pupil, typical subject wavefront-based optics, and eccentricity-based cone mosaics (Cottaris et al., 2019). Bottom panels: Ratios of CSFs with respect to the reference CSF, which is computed using the SVM-Template-Linear observer in the absence of fixational drift (gray disks). (A). CSFs computed using the SVM-Template-Linear computational observer in the absence (gray disks) and presence (red disks) of fixational drift. (B) CSFs computed using the SVM-Template-Energy observer in the absence (red disks) and presence (blue disks) of fixational drift. Gray disks in panel B replicated from panel A.
