MathWorks Inc two-dimensional image correlation coefficient
Stimulus-image correlation. (A) Schematic representation of the calculation of image correlation coefficients as a metric for retinal image quality. The two-dimensional image correlation <t>coefficient</t> is obtained by computing the cross-correlation for two stimuli, one convolved with the diffraction limited PSF, the other one convolved with the eye's individual PSF. (B) Stimulus image correlation coefficients are plotted as a function of Landolt (left)/Vernier (right) acuity thresholds (n = 31). Data points of the two subjects with the highest and lowest Strehl ratio are plotted in light blue and magenta, respectively (compare ). Only Landolt acuity correlates significantly with the image correlation coefficients, shown in the lower left corner of each plot.

Figure Lengend Snippet: Stimulus-image correlation. (A) Schematic representation of the calculation of image correlation coefficients as a metric for retinal image quality. The two-dimensional image correlation coefficient is obtained by computing the cross-correlation for two stimuli, one convolved with the diffraction limited PSF, the other one convolved with the eye's individual PSF. (B) Stimulus image correlation coefficients are plotted as a function of Landolt (left)/Vernier (right) acuity thresholds (n = 31).

Only Landolt acuity correlates significantly with the image correlation coefficients, shown in the lower left corner of each plot.

Article Snippet: The two-dimensional image correlation coefficient (MATLAB, MathWorks, Natick, MA; 2-D correlation coefficient corr2 ) calculated between both images is then used as the retinal image quality metric.
