Recent research in visual saliency has established a computational measure of perceptual importance. In this paper we present a visual-saliency-based operator to enhance selected regions of a volume. We show how we use such an operator on a user-specified saliency field to compute an emphasis field. We further discuss how the emphasis field can be integrated into the visualization pipeline through its modifications of regional luminance and chrominance. Finally, we validate our work using an eye-tracking-based user study and show that our new saliency enhancement operator is more effective at eliciting viewer attention than the traditional Gaussian enhancement operator.
近期关于视觉显著性的研究建立了一种感知重要性的计算度量。在本文中，我们提出了一种基于视觉显著性的算子，以增强体数据中的选定区域。我们展示了如何在用户指定的显著性场中使用这样的算子来计算一个强调场。我们进一步讨论了如何通过修改区域亮度和色度将强调场集成到可视化管道中。最后，我们通过基于眼动追踪的用户研究验证了我们的工作，并表明我们新的显著性增强算子在吸引观众注意力方面比传统的高斯增强算子更有效。
