Cylin-Painting: Seamless {360\textdegree} Panoramic Image Outpainting and Beyond

Understand

Image outpainting gains increasing attention since it can generate the complete scene from a partial view, providing a valuable solution to construct {360\textdegree} panoramic images.

• As image outpainting suffers from the intrinsic issue of unidirectional completion flow, previous methods convert the original problem into inpainting, which allows a bidirectional flow.
• However, we find that inpainting has its own limitations and is inferior to outpainting in certain situations.
• The question of how they may be combined for the best of both has as yet remained under-explored.
