Query: Painting Outside as Inside: Edge Guided Image Outpainting via
  Bidirectional Rearrangement with Progressive Step Learning   Image outpainting is a very intriguing problem as the outside of a given
image can be continuously filled by considering as the context of the image.
This task has two main challenges. The first is to maintain the spatial
consistency in contents of generated regions and the original input. The second
is to generate a high-quality large image with a small amount of adjacent
information. Conventional image outpainting methods generate inconsistent,
blurry, and repeated pixels. To alleviate the difficulty of an outpainting
problem, we propose a novel image outpainting method using bidirectional
boundary region rearrangement. We rearrange the image to benefit from the image
inpainting task by reflecting more directional information. The bidirectional
boundary region rearrangement enables the generation of the missing region
using bidirectional information similar to that of the image inpainting task,
thereby generating the higher quality than the conventional methods using
unidirectional information. Moreover, we use the edge map generator that
considers images as original input with structural information and hallucinates
the edges of unknown regions to generate the image. Our proposed method is
compared with other state-of-the-art outpainting and inpainting methods both
qualitatively and quantitatively. We further compared and evaluated them using
BRISQUE, one of the No-Reference image quality assessment (IQA) metrics, to
evaluate the naturalness of the output. The experimental results demonstrate
that our method outperforms other methods and generates new images with
360{\deg}panoramic characteristics.
