Perceptually Driven Simplification Using Gaze-Directed Rendering

David Luebke, Benjamin Hallen, Dale Newfield & Benjamin Watson
We present a unique polygonal simplification method grounded in rigorous perceptual science. Local simplification operations are driven directly by perceptual metrics, rather than the geometric metrics common to other algorithms. The effect of each operation on the final image is considered in terms of the contrast the operation will induce in the image and the spatial frequency of the resulting change. Equations derived from the psychophysical studies determine whether the simplification operation will be perceptible;...
