This paper describes a mostly automatic method for taking the out-
put of a single panning video camera and creating a panoramic
video texture (PVT): a video that has been stitched into a single,
wide field of view and that appears to play continuously and indef-
initely. The key problem in creating a PVT is that although only a
portion of the scene has been imaged at any given time, the out-
put must simultaneously portray motion throughout the scene. Like
previous work in video textures, our method employs min-cut opti-
mization to select fragments of video that can be stitched together
both spatially and temporally. However, it differs from earlier work
in that the optimization must take place over a much larger set of
data. Thus, to create PVTs, we introduce a dynamic programming
step, followed by a novel hierarchical min-cut optimization algo-
rithm. We also use gradient-domain compositing to further smooth
