虚拟现实和沉浸式影院等各种应用都需要高图像质量、低渲染延迟和一致的深度提示。4D光场显示器支持焦点调节，但渲染成本高于2D图像，导致延迟更高。人类视觉系统可以分辨中央凹中比周边中更高的空间频率。最近的2D中心凹渲染方法利用了这一特性，以降低计算成本，同时保持感知质量。受此启发，我们提出了foveated 4D光场，通过研究它们对3D深度感知的影响。基于我们的心理物理实验和理论分析的视觉和显示带宽，我们制定了一个内容自适应的重要性模型在4D光线空间。我们验证了我们的方法，通过建立一个原型光场显示器，可以呈现只有16% - 30%的光线，而不影响感知质量。
A variety of applications such as virtual reality and immersive cinema require high image quality, low rendering latency, and consistent depth cues. 4D light field displays support focus accommodation, but are more costly to render than 2D images, resulting in higher latency. The human visual system can resolve higher spatial frequencies in the fovea than in the periphery. This property has been harnessed by recent 2D foveated rendering methods to reduce computation cost while maintaining perceptual quality. Inspired by this, we present foveated 4D light fields by investigating their effects on 3D depth perception. Based on our psychophysical experiments and theoretical analysis on visual and display bandwidths, we formulate a content-adaptive importance model in the 4D ray space. We verify our method by building a prototype light field display that can render only 16% -- 30% rays without compromising perceptual quality.
