Abstract |
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 analyze
the limits of our approach and failure-case artifacts. |
