Extracting high-quality dynamic foreground layers from a video sequence
is a challenging problem due to the coupling of color, motion, and
occlusion. Many approaches assume that the background scene is static
or undergoes the planar perspective transformation. In this paper,
we relax these restrictions and present a comprehensive system for
accurately computing object motion, layer, and depth information.
A novel algorithm that combines different clues to extract the foreground
layer is proposed, where a voting-like scheme robust to outliers
is employed in optimization. The system is capable of handling difficult
examples in which the background is nonplanar and the camera freely
moves during video capturing. Our work finds several applications,
such as high-quality view interpolation and video editing.
