The retina is a part of the central nervous system in the vertebrate and plays important roles in early stage of visual information processing. The retina computes the image with a completely different algorithm/architecture from the one, which most engineers are familiar with using the unique algorithm/architecture, the retina can perform real-time image processing with very low power dissipation.
