Virtual Eye: A Spatial-Temporal Bottom-Up Eye Sensitivity Model, Todd Goodall

Video quality and compression models use the
spatial contrast sensitivity function (CSF), which is solved
based on a linear system approximation. This function measures
the eye’s sensitivity to sinusoid gratings, ignoring the subtle
connectivity and inhomogeniety of cell density across the
visual field. Non-linear aspects of the eye, such as the change
in frequency sensitivity with changing illumination, are not
captured by this simple approximation. We propose Virtual
Eye, a bottom-up approach that models the spatio-temporal
dynamics of the eye across the visual field. Each functional
retinal cell layer in the eye is modeled using non-uniform spatial
cell responses, which …
