我们提出了一个新的感知渲染流水线，考虑到由于对比度和空间频率的视觉掩蔽。我们的框架预测了由部分遮挡和阴影引起的对象间场景级掩蔽。它专为交互式应用程序而设计，并在GPU上高效运行。这是通过使用基于层的方法以及基于GPU的阈值图的有效计算来实现的。我们建立在这个预测框架，引入一个基于感知的细节控制算法的水平。我们进行了一项感知用户研究，表明我们的感知管道生成的结果与用户感知的结果一致。我们的研究结果表明，由于频率和对比度的掩蔽，如由于树木或树叶，或由于高频阴影掩蔽场景的质量显着改善。
We present a new perceptual rendering pipeline which takes into account visual masking due to contrast and spatial frequency. Our framework predicts inter-object, scene-level masking caused by partial occlusion and shadows. It is designed for interactive applications and runs efficiently on the GPU. This is achieved using a layer-based approach together with an efficient GPU-based computation of threshold maps. We build upon this prediction framework to introduce a perceptually-based level of detail control algorithm. We conducted a perceptual user study which indicates that our perceptual pipeline generates results which are consistent with what the user perceives. Our results demonstrate significant quality improvement for scenes with masking due to frequencies and contrast, such as masking due to trees or foliage, or due to high-frequency shadows.
