Adaptive image sampling based on the human visual system

摘要

Everyone agrees that the human visual system is able to perform complex tasks apparently without the slightest effort. The sharpness of sght of the human visual system is closely linked to the number and the density of visual cells. The greatest visual acuity is provided by the fovea which is a small retinal area located in the axis of the human eye pupil. Beyond this particular area, the acuit falls roughly in inverse proportion to the visual angle.
