要旨:
We propose an approach to interactively explore video textures
from different viewpoints. Scenes can be played back continuously
and in a temporally coherent fashion from any camera location
along a path. Our algorithm takes as input short videos from
a set of discrete camera locations, and does not require contemporaneous
capture � data is acquired by moving a single camera. We analyze this data to
find optimal transitions within each video (equivalent to video textures) and
to find good transition points between spatially distinct videos. We propose a
spatio-temporal view synthesis approach that dynamically creates intermediate
frames to maintain temporal coherence. We demonstrate our approach on a variety
of scenes with stochastic or repetitive motions, and we analyse the limits of
our approach and failure-case artifacts.
