Low-level brightness-contrast illusions and non classical receptive field of mammalian retina

摘要: Among the visual illusions there is a class, which known as low-level brightness contrast illusions. These are processed probably at retinal ganglion cell without necessitating any intervention from higher order cortical processing. The concept of classical receptive field cell, derived early physiological studies, prompted idea that "Difference Gaussian" or DoG model might reproduce output cell. In spite its many successes, fails to explain some these low level On basis recently available data, we have modified and shown efficacy in understanding illusions, phenomenon may potential application designing new robust capturing display systems.
