Computational model of the human eye for intelligent systems

The knowledge of the spatiotemporal sensitivity of the human eye can be essential for those practical applications where the communication of an informatical system and a human subject can be crucial (topics: cognitive informatics, cognitive infocommunication), such as intelligent video-coding, driving assistant systems or intelligent instrumental boards. In this paper we will present the spatiotemporal sensitivity of the human eye for achromatic stimuli at photopic light levels. To our knowledge, it is the first comprehensive model that: (1) considers the spatiotemporal transfer function of P and M ganglion cells along the retina, (2) contains the fast adaptation mechanisms (contrast gain control and luminance gain control) and (3) discusses the role of the receptor and post-receptor light adaptation separately.
