Paper Abstract

We analyze the characteristics of a synthetic sensor comparable with respect to field width and resolution to the primate visual system. We estimate that 150 pixels are sufficient using a logarithmic sensor geometry and demonstrate that this calculation is consistent with known characteristics of biological vision e. g. the number of fibers in the optic nerve. To obtain the field width and resolution of the primate eye with a uniform sensor requires between iOiO'' times the number of pixels estimated for the comparable log sensor. Another interesting observation is that the field width and resolution of a conventional 512x512 sensor can be obtained with around 5000 pixels using the log geometry. We conclude with consideration of the prospects for achieving human-like performance with contemporary VLSI technology and briefly discuss progress on space-variant VLSI sensor design.
