MNCSI: Shunting Inhibition and Contrast Enhancement Vision Chip
Contrast enhancement is an important visual processing task in biological retina. Its task is to emphasize interesting features in the image, reduce noise, and make best use of available communication bandwidth by reducing the dynamic range of the image. Several computational and biological models for contrast enhancement were described in Section 2.3. VLSI implementations of contrast enhancement circuits were also presented in Section 5.4.5.
