人类的大脑会自动尝试根据视点和/或观察到的物体或场景的合理运动来解释来自我们眼睛的物理视觉输入[Ellis 1938;格雷厄姆1965年;Giese and Poggio 2003]。在物理世界中,定义合理运动的规则是由时间相干性、视差和透视投影设定的。然而,我们的大脑拒绝在它认为合理的运动中受到无情的物理定律的约束。图像变形实验,其中不自然的,不可能的中间图像被插入,证明在某些情况下,我们愿意接受嵌合图像作为真实的,已知物体图像之间的合理过渡阶段[Beier和Neely 1992;Seitz and Dyer 1996]。或者想想卡通动画,在很长一段时间里,它们都是手绘的艺术作品,不需要屈服于物理正确性。我们工作的目标是利用这种感知的自由来进行时空插值,也就是说,在静止图像之间产生过渡,我们的大脑在移动的3D世界中接受这些图像,认为它们是合理的运动。
The human brain automatically attempts to interpret the physical visual inputs from our eyes in terms of plausible motion of the viewpoint and/or of the observed object or scene [Ellis 1938; Graham 1965; Giese and Poggio 2003]. In the physical world, the rules that define plausible motion are set by temporal coherence, parallax, and perspective projection. Our brain, however, refuses to feel constrained by the unrelenting laws of physics in what it deems plausible motion. Image metamorphosis experiments, in which unnatural, impossible in-between images are interpolated, demonstrate that under certain circumstances, we willingly accept chimeric images as plausible transition stages between images of actual, known objects [Beier and Neely 1992; Seitz and Dyer 1996]. Or think of cartoon animations which for the longest time were hand-drawn pieces of art that didn't need to succumb to physical correctness. The goal of our work is to exploit this freedom of perception for space-time interpolation, i.e., to generate transitions between still images that our brain accepts as plausible motion in a moving 3D world.
