计算摄影包含多种成像技术，但其中许多技术执行的核心操作之一是计算图像差异。计算这种差异的直观方法是顺序捕获几个图像，然后联合处理它们。通常，这种方法在记录动态场景时会导致伪影。在本文中，我们介绍了一种快照差成像方法，直接实现在新兴的飞行时间相机的传感器硬件。通过各种示例，我们证明了所提出的快照差分成像技术对于直接全局照明分离、空间和时间图像梯度的直接成像、直接深度边缘成像等是有用的。
Computational photography encompasses a diversity of imaging techniques, but one of the core operations performed by many of them is to compute image differences. An intuitive approach to computing such differences is to capture several images sequentially and then process them jointly. Usually, this approach leads to artifacts when recording dynamic scenes. In this paper, we introduce a snapshot difference imaging approach that is directly implemented in the sensor hardware of emerging time-of-flight cameras. With a variety of examples, we demonstrate that the proposed snapshot difference imaging technique is useful for direct-global illumination separation, for direct imaging of spatial and temporal image gradients, for direct depth edge imaging, and more.
