Saliency determination for computer graphics : an experimental approach

Abstract

In the computer graphics realm complex objects are abundant, but often need to be simplified in order to be displayed interactively. As the human visual system is far from flawless, advantage can be taken of its weaknesses by using perceptually adaptive graphics during the rendering of images or animations. In this thesis, we attempt to establish if visual fidelity can be improved by emphasising the detail of salient parts of models, found with an eye-tracking device, at the expense of unimportant areas. In an extension to this, we compared the effect of tasks on eye-movemerits in a real and virtual environment.
