Video extrapolation is the task of extending a video beyond its original field
of view. Extrapolating video in a manner that is consistent with the original
video and visually pleasing is difficult. In this work we aim at very wide
video extrapolation which increases the complexity of the task. Some video
extrapolation methods simplify the task by using a rough color extrapolation. A
recent approach focuses on artifact avoidance and run time reduction using
foveated video extrapolation, but fails to preserve the structure of the scene.
This talk introduces a multi-scale method which combines a coarse to fine
approach with foveated video extrapolation. Foveated video extrapolation
reduces the effective number of pixels that need to be extrapolated, making the
extrapolation less time consuming and less prone to artifacts. The coarse to
fine approach better preserves the structure of the scene while preserving
finer details near the domain of the input video. The combined method gains
improvement both visually and in processing time.
