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.
