本文提出双眼分视凹雕渲染，通过一只眼模糊另一只眼锐化，在VR中测量并建模眼间频率差异，进而增强凹雕渲染的高频信息。
AI 中文摘要
视觉感知中的眼间差异在由大脑融合时可能诱发多种效应。例如，先前的研究发现，精心设计的局部细节双眼差异可以提高对比度。研究还发现，当两个刺激的频率内容略有不同时，模糊抑制会导致融合感知通常由更清晰的图像主导。在本文中，我们开发了一个心理物理学框架，用于测量自然图像刺激在视野中具有眼间频率差异时的感知。为此，我们研究了双眼分视凹雕渲染（dichoptic foveation）的效果，我们将其定义为对一只眼睛应用模糊，同时对另一只眼睛应用锐化滤波器。刺激在虚拟现实（VR）头戴式显示器（HMD）中呈现，并放置在不同的视网膜偏心率处。研究数据被缩放为感知的刚好可察觉差异（JOD）量表，并拟合了一个4D模型；我们的结果表明，眼间频率差异可以很好地由简单计算模型描述。我们将该模型应用于一个真实的VR场景中，自由探索360°视频，通过双眼分视地增强高频信息来改进基础的凹雕渲染系统。
英文摘要
Interocular differences in visual perception can induce a variety of effects when fused by the brain. For example, prior works have found that carefully crafted binocular differences in local detail can improve contrast. It has also been found that when the frequency content of two stimuli are slightly different, blur suppression leads to a fused percept that is typically dominated by the sharper image. In this paper, we develop a psychophysical framework to measure the perception of natural image stimuli with interocular frequency differences across the visual field. To this end, we study the effect of dichoptic foveation, which we define as the application of blur to one eye and a simultaneous sharpening filter to the other. Stimuli were viewed in a virtual reality (VR) head-mounted display (HMD) and placed at different retinal eccentricities. Study data were scaled to a perceptual just objectionable difference (JOD) scale, and a 4D model was fit to it; our results suggest that interocular frequency differences can be well described by a simple computational model. We applied the model in a realistic VR scenario with free exploration of 360° videos to improve a base foveated rendering system by enhancing high frequency information dichoptically.
