Abstract

The knowledge of human visual system (HVS) enables more efficient image rendering by overcoming physical constraints of display devices. This talk presents a number of successful examples of embedding HVS models into real-time rendering pipelines. In particular, I discuss the problem of improving the appearance of highlights and light sources by boosting their apparent brightness using the temporal glare technique. Also, I discuss how to overcome physical contrast limitations of display devices by using the 3D unsharp masking technique to boost the apparent contrast. Also, I present techniques for apparent resolution enhancement, which enable showing image details beyond the physical pixel resolution of the display device. Finally, I discuss the role of perception in context of stereovision and accommodation/vergence conflict reduction.
