Research Abstract

We developed a computational model of the cone mosaic based on the physiological and anatomical characteristics. The present model incorporated the spectral sensitivities of three types of cones, as well as the nonuniform spatial distributions of cones. The cone mosaic was generated by a stochastic algorithm to reproduce the nonuniformity. The present model covers a visual angle of 60 degrees with 2,000,000 cones. The model allows us to analyze how color information is processed in the cone mosaic. In simulation, we produced various types of cone mosaics by changing the subtype cone ratio and/or the spectral sensitivities. We analyzed how the cone mosaic limits our ability to infer the spatial and color information processing present in the retinal image. We also extended the model to include the ganglion cells for analyzing the input-output relationships in the retina.
