Decoding method results corroborated on a second RGC data set. (A) Representative outputs from the decoding algorithm compared to those from a simple linear decoder. (B) Comparison of pixel-wise test correlations and SSIM values between deblurred and linear decoder outputs and against combined decoder outputs, respectively. The second data set consisted of the responses of 1987 RGC units to 10,000 images, prepared in an identical manner as the first data set. The superiority of nonlinear decoding with deblurring is apparent.
